If you sometimes get arming tones, and sometimes don't and you're running really hot sometimes and sometimes not.....you have a wiring problem, definitely. Pull on all of your bullet connectors to make sure the solder joints are still tight. Make sure all the connections are fully seated and clean. 1maxdude mentioned he saw black spots, definitely a sign of arcing. If you see any of the above, that's the source of your problem
