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.

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?
