I believe if you have a short you should blow a fuse. But if your engine is dying you probably have a bad alternator and/or battery.
make sure body ground to motor is still connected.
This happened to me in a 95 Toyota Tercel and the cause was for the most part dirty battery connections, when the electrical load was raised the alternator could not immediately keep up and required a moment to adjust, but with a bad battery connection (probably the Positive in my case) it couldn't temporarily draw enough power from the battery to still fire the spark plugs hence the immediate stall.
I would replace the headlight switch as Ford has had their share of these problems.
The car has automatic headlights....they go on and off when it gets light or dark out...they will also stay on for up to 3mins after you shut the car off depending on how the twilight sentenal switch is adjusted. And to take out the headlight switch in the door you have to take apart the door pannel
Answer I had a similar problem when I put a CD player in my 92 explorer. The problem was that somehow I used the hot wire from the headlights. I simply just rewired the power wire and problem solved. First of all I would check the power source. If you didn't use a wiring harness some of the 12v power is discontinued when you turn the headlights on. Using either a voltmeter or testlight check for a constant power source. THE MOST COMMON CAUSE OF THIS IS CONNECTING YOU VEHICLES DASH LIGHT WIRE TO THE GROUND ON THE STEREO
First....use an OEM sensor...1996 Jeep Grand Cherokees have been known to not work properly on non- OEM Crankshaft sensors. Excessive heat can cause it to go bad. Proper installation is critical. Also there is a joint in the wiring from the sensor to the PCM. It can corrode and sometimes cause stalling of the engine whether the engine is cold or hot. PCM could be going bad.
The first thing that I would check is the wiring and the temp sensor @ the engine. Sorry but I do not know where the sensor is located on the engine. Usually they are not too hard to locate. i would replace temperature sender usual located near front of engine near thermostat housing
Check to see that all other lights work on the neon. Check for a headlight fuses, relay, and a bad switch. Check for any loose wiring that can cause power loss to the headlight.
If both headlights in your 2003 Hyundai Sonata stopped working simultaneously, it could be due to a blown fuse, a faulty headlight relay, or a wiring issue. Check the fuse box for a blown headlight fuse, as this is a common cause. If the fuse is intact, inspect the headlight bulbs and wiring for any damage or corrosion. If the problem persists, it may require a closer inspection by a professional.
A blown fuse will cause the 1995 Ford Taurus headlight to stop working. The fuse box can be found in the engine compartment.
The headlights in a 1995 Jeep Cherokee may stay on due to a malfunctioning headlight switch, a faulty relay, or a problem with the auto-off feature, if equipped. Additionally, if the vehicle has a switch that controls the headlights, it might be stuck in the "on" position. Wiring issues or a short circuit could also cause the headlights to remain illuminated. Checking the switch, relays, and wiring for faults is a good first step in diagnosing the issue.
If the headlights on a 2000 Mercury Villager are not working, potential causes could include a blown fuse, a faulty headlight relay, or burned-out bulbs. Additionally, issues with the wiring or connections, such as corrosion or loose terminals, could disrupt power to the headlights. It's also worth checking the headlight switch for any faults. Conducting a systematic check of these components can help identify the issue.
you need to check your wiring from the headlights bac to where it starts. it could just be a bad ground or you might have a break in the power wire to that light
To ensure the headlights on a Daewoo Matiz turn off when you turn off the engine, you can check the headlight switch settings. Make sure the switch is in the "off" position before turning off the ignition. If the headlights still remain on, inspect the headlight relay or consult the vehicle's manual for any specific settings or features that may cause the lights to stay on after the engine is turned off. If the problem persists, consider seeking assistance from a mechanic.
headlight switch is probaly your trouble
Run a ground wire to that headlight. If it gets brighter, there is a problem with the ground in the wiring harness.

bad headlight switch.
Dim headlights that brighten when you pull the lever for flash to pass may indicate a problem with the headlight switch or wiring. It could be due to a poor connection, corrosion, or a failing headlight relay that affects the power supplied to the headlights. Additionally, the issue might stem from a weak battery or alternator, failing to deliver sufficient voltage under normal conditions. Checking the electrical connections and components related to the headlight circuit would be a good first step in troubleshooting.
