I agree, this sounds like something loose where transmitting can burn it. Most of the time this has been something out in the weather. Sometimes something so simple as a PL259 that didn't get tightened up. Has also been ruined relay contacts in the amp subjected to hot switching. Causes for that are diverse. Very easy to do if you are using a hot mic and VOX.
