Will not restart until it cools off some.

That sounds low for volts while running.

If it were me before I do too much tail chasing I'd remove, clean, inspect, and repair or replace your cables individually including your main battery cables. I say individually so there's no confusion as to where they get reinstalled.

One bad connection and you will never get it right. Clean all contact points and connectors and while cleaning/inspecting the cables, replace any that look questionable. Then check your voltage again and you should see an increase if the generator is healthy. Pay special attention to your main ground point!
