Re: No start when hot

when you hit the key do the dash lights dim a tad? its highly likely your starter has gone south. my starter would do exactly the same thing. i replaced the starter and no issues.

Try an ignition control module. located under distributor cap under the rotor - about $45

If it would stall when hot, then I would guess ignition module.
But I think the issue is restarting after turning the ignition off on purpose, in which case it's likely the starter.

Re: No start when hot

Sounds like a heat soaked starter. A module when getting to hot would cause hesitation , breaking up , etc..
