Heres what you need to do to start with. If you are mechanically inclined, when it stalls, check for spark on the #1 cylinder. If you have no spark there, it is likely the CPS or Crankshaft Position Sensor has gone bad, a common issue, and will need to be replaced.

Engine shuts off after driving 45 min when parking in reverse.But 15 min before this engine and slippery road icon comes on.2 hrs later car starts and drives normal then shuts off again 45 min later.


most commonly found problem relates to an electronic component heating up and shutting down. Have you checked to confirm there is fuel pressure when the vehicle shuts off. Is the check engine light on. Have you checked codes ? I suggest hooking up a fuel pressure gauge and letting vehicle run till it shuts off while monitoring the fuel pressure. If you loose fuel pressure, next step is to confirm there power going to the pump, if there is power going to the pump with no fuel pressure replace pump. Another suggestion would be to check for spark when vehicle stops running to eliminate an ignition problem. good luck

I have 97 Pontiac sun fire runs for 15 min then die will not start for about 15min after that


Fuel pump going out. Once it gets warm after 15 mins the o rings loosen up and cause it to loose prime and shut off. After cooling for 15 mins they have shrunk enough to build pressure again.

Quits after warm up wont restart


sounds like you have a fuel pump problem, fuel pumps will usually get hot and then shut off allowing it to sit 30 mins lets the pump cool down allowing it to start pumping, the way you can test it is get a can of starting fluid the next time it quits raise your hood and spray some fluid down into the throttle body and if it starts and then dies it is most likely your fuel pump, hope this helps.
