Q: Car runs and then dies

asked by on

My car runs for a while and then cuts off.

Hello. This comes up fairly often on this vehicle. If the Jeep runs fine for a while and then simply turns off and may not restart right away this is usually caused by a faulty auto shut down (ASD) relay which would need to be replaced. This relay is used to shut off circuits such as the ignition and fuel system at specified times. The relay fails and this occurs. A mechanic would start by testing the relay. If the relay is fine then it may be a bad crank position sensor or a fuel pump circuit that is failing.
