I have a 1998 Plymouth grand Voyager, that is driving my Crazy. I It die at various times and not through a code. It happens mostly at first start up in thirty seconds or less, but at times the motor dies at speed or at a stop light. I have done a lot of testing, replaced numerous sensors, checked harnesses, and connections with no solution. I need to a recommendation or volunteer to check this van out!

 

If you replaced the cam and or crank sensor with an aftermarket sensor; most cause this problem since the magnets are not strong enough to give a reliable signal to the EEC. If you issue is at idle, clean the throttle body and check the IAC.

 

It turned out to be the PCM.
Thank you, Nick
