1995 Olds 88 with 3.8L series II engine: engine kills (no spark) after thorough warm-up or will not restart after heat-soak (turned off 20 mins after running). Needs 6 hours cooling to restart. Could a bad cam position sensor do this? It is NOT: cranshaft position sensor, engine control module, ignition control module, coil packs or MAF sensor. Voltage at ICM pink wire (12V power) is good.

Bad cam sensor should set a code
check for codes and if any, repair as needed 1st
check if have security system light on and or flashing
if all ok
suspect mem-cal inside PCM

Check Engine Light does not come on after engine dies. Since the engine block is the slowest thing to cool off, I wondered if the cam sensor might be the culprit. Is it capable of killing engine?
