Mike;
I too was hunting down a ghost wiring issue "no start after engine gets hot". I chased everything, grounds, resistance wires. Bottom line I changed the under-hood headlight harness and engine harness with the engine in. Had to snake it in a few places otherwise worked fine. Never could isolate the resistance issue. I imagine buried somewhere in the harness is a burnt wire that goes open or drastically increases resistance after running and hot. I know you might not want to hear this but if I had to do it again, I'd buy new harnesses and just replace them. No use burning a car to the ground for want of a good harness. Now I know yours is not that drastic however the electrical harnesses are 47 years old. I would also recommend if you can't find the issue and are on a budget remove the harnesses unwrap them and troubleshoot yourself.
