It sounds like half of your PA shuts down somewhere close to the final stage transistors. Could it be a bad soldered connection somewhere which loses connection after brief warm-up? Or a partially stripped wire in one of symmetric transformers? I'd start with checking all the connections around PA transistors in final stage. (I had similar experience with a powerful AF amplifier long time ago, but there was another hint - audio was badly distorted.)
