Hey,
I have a 96 caravan with an unusual problem. After it warms up to its normal temperature and i come to a complete stop the engine will shut off. The electronics will stay on and to get it to start again i just turn the key to off and start it back up.

thanks in advance

 

Will it coast to a stop with the transmission in "nuetral"? If so it could be the lock-up torque converter isn't unlocking and killing the engine.
It could also be the idle air control valve sticking shut.This is on the throttle body and can be cleaned by using carb cleaner sprayed into the bypass air tube.
