I would also check for dc offset at the speaker terminals. put your MM on dc and on the lowest range, let the amp warm up and then take a measurement at both terminals..
Should be less than say 20Mv this may be a dc offset problem certainly from the first episode it is suspicious. Other than that it could be anything like high ESR caps shorting the supply , failed rectifier or bad relay or latching cct for the relay soft start.
Needs a tech
