STALL NO START WHEN WARM

1989 Pontiac 6000

Engine Performance problem
1989 Pontiac 6000 6 cyl Front Wheel Drive Automatic 135, 00 miles

Vehicle can be driven for about 10 minutes then stalls any speed even idling. Will crank with no start until dead cold again. No codes. Have fuel pressure at rail, spark at plugs. No injector pulse. Have replaced ignition module. Am hesitant to replace crank sensor because spark is constant even after vehicle stalls. Borrowed a scan tool and verified rpm in data while cranking ect at 109 F No out of spec readings noted in main data. Suspect ecm or wiring anything wierd sensor wise you've heard of or a likely fail point for wiring? Thanks -Bill

There is nothing out of the ordinary for these vehicles. Chances are you hit the nail on the head, the ECM.

Appreciate your response, problem ended up being a shorted injector shutting down the injector driver in the ecm. Took replacing the ecm to figure that out though.
