fuel pump or crank sensor
A lot of possible causes, I recommend a careful investigation.
Yes, some can actually shut down the computer and make your car unable to start.
the car alarm will allow the car to start and run briefly then "shut down".
press it down until it clicks.
Viper Car Alarms will also shut the engine down.
it can be different things but u can start checking with IAC or the fuel
The Oxygen sensor, or the IAT Sensor is telling you Ecu to shut down the car. Its running to hot. Or you have a pressure hose that has a leak or has come off.
Timing belt is close to breaking ....or belt is out of adjustment
Hold down the clutch when sitting still or going too slow for that gear.
Replace the battery or the carbarreta
I'd check all the fuses
the car will break or shut off automaticly
