97 tand c runs fine then shuts off
 

hi im new 97 town and country,runs fine for 15 min. then stops,have no fire to coil pack,15 min. later runs fine again,any help i would appreciate

codes in the computer?

there are no codes thanks for help,it is a 3.8 motor

If the fuel injectors are dead too that points to an automatic shutdown due to loss of crank or camshaft sensor signal. Could be the sensors themselves, poor connections or the wire harness carrying the signal. If it's only no coil power it points to loss of power out of the PCM meaning a bad wire to the coil, poor connection or a bad PCM.

The OBD fault detect system is far from fool proof. Components often fail without generating a code and a check engine light.

thank you very much, gives me somewhere to start.hopefully i will have some time in the next few days to check it out.

do i have to have noid tester to check pulse at injector connector?
