It could be shutting off because of the heat sensor on the magnatron is over heating because of a bad capacitor or diode or the power transformer its self. This is a call for the service man BUT you know these days a microwave like this cost a couple of hundred bucks maybe a little more too. But it will possibly cost 150 or so if not more to fix the average microwave. If you really like it, then see if you can have it estimated BUT its not for the handy man to try to trouble shoot as theres extremly high voltage in these puppys even when they are not plugged in!! Good luck
