Car starts perfectly when cold, starter just clicks when car is hot

I have a 1992 corvette, the starter and battery are brand new, and the car starts perfectly when its cold. But after driving for about ten minutes, it will not start again if I shut it off. I have to wait for it to cool and then it will start perfectly again. I have a heat wrap on the starter and that did nothing. However, if I jump the car with another car while its hot the car while start.

I have cleaned the ground behind the battery, the ground strap behind the battery and where it connects on the engine.
It sounds like something is getting heat soaked. Did you wrap the solenoid too? Back in my hot rod days we'd connect the starter lug to the solenoid with a brass strap and take the solenoid to a Ford type relay. You'd turn the key and energise the relay which would put power to the starter and solenoid both. Don't laugh, it worked

How would I connect the solenoid to Ford type relay? Would I just splice it into the wire connecting to the s terminal from the neutral safety switch?
Yeah the solenoid is wrapped as well

By starter lug, do you mean a bolt holding the starter in.

No. The stud that holds the positive "hot" wire. This is an idea of what I did to get rid of the "hot" starter problem

If starter & solonoid is wrapped & you are still having issues . I would go with heaver gage ground & power cables ( mine were made by Napa ) & possible battery with higher cranking amp. It cured my problems
Just throwing this out there. Could be a bad starter I know you said it was new. Or was it a reman. A while back I went through six reman alternators before they finally gave me a new one just to get rid of me. All the reman alternators had Faulty voltage regulators.
