Car runs, gets hot, then dies. Cant restart until cooler.

swap out your starter 1nce and watch where the connections are sitting check your fusable link are you using an MSD box it may be sending a false reading make sure it is shielded from any heat source , change out your ballast resistor if you are still running 1 with an MSD . MSD 6al instructions say to bypass the ballast and last , good luck because trouble shooting an electrical problem is the worst problem I ever had in a 40-50 ye4ar old car .make sure you put an extra ground to the motor and the frame .
make sure it is an electrical problem and not a fuel issue. Mopar did have some really bad exhaust manifold designs, for instance the 64 - 66 barracuda"s GL let us know what you find
