What do the plugs look like color wise? Where is the timing set at? Vacuum leak anywhere?

Timing chain. When it cools off enough to restart, put a timing light on it. If the marks seem to move back and forth the least bit, the chain is shot.

Sounds like a ignition issue, usually a timing chain will just change at once, it won't go back and forth.

I would say brain box. (Acts up when it gets hot)

Throw another brain in the glove box, and the one on the car will work perfect!
