Hard starts or stalls in the morning usually indicate a problem with the fuel system, because a couple special things need to happen at start up in order to get the car up and running.
If your car is carbureted, meaning the air and fuel are mixed together in a carburetor and then this mixture is injected into the cylinders, it uses a choke. When cold, the choke keeps a butterfly valve in the carburetor shut, creating a fuel mixture with lots of fuel and a little air. Then as the car warms up the choke slowly opens, allowing more and more air into the fuel mixture. In order to start with a cold engine a car requires a rich fuel mixture with more fuel than normal running requires, so if there is a problem with your choke its usually noticed when your car stalls after first starting it in the morning.
If your car is carbureted, I would try pumping the gas pedal a once or twice before you start it the first time. This will both reset the choke if it failed to do it on its own, and add a little extra gas to the cylinders to aid the cold start.
If your car is fuel injected, pumping the gas pedal once before starting it may help, but then it may not. Fuel injected systems perform the same functions as a carberator, but they do it all electronically, and are much more expensive to fix because they are far more complex.
Hope this helps!

If it is stalling when putting it into gear but not while idleing I would check your mass air flow sensor. It may need to be cleaned or replaced. If it is stalling when putting it into gear but not while idleing I would check your mass air flow sensor. It may need to be cleaned or replaced.

Probably a stuck solenoid.
time to get a watch! :)
car starts but shut off while driving
The pathfinder may be running to rich. It could be the 02 senser,air flow senser, or bad gas
12:00:01AM is when the morning starts. Some people say that morning starts at 4:00am or 6:00am because they are usually asleep. But it is 12:00:01 AM, the second after midnight.
Check the fuel pump?
It sounds like your alternator is no longer recharging your battery. You probably need a new alternator.
There is most likely something in the gas tank. When the car starts the fuel pump starts sucking in fuel and when the trash gets to it the gas will not be able to flow through the clogged pump so the car stalls. When it stalls the fuel pump stops suction and the trash comes out allowing it to start again.
my suburban wont start
the idle jet in the carb is blocked and needs to be cleaned out and reset
It is probably the alternator. That is what keeps the battery running to the rest of the vehicle. It is probably the fuel to air mixture or a vacum leak. If you hear a hiss when it is running then its vacum if it just slowly stalls when you don't give it throtle then it is fuel.
Possibly Crankshaft Position sensor
could be distributer module
won't stay running starts and goes then stalls Sounds like might be a float ,fuel filter or maybe just needs a good cleaning. Hope this helps.
