Generator fried microwave after gen shut down several times

Thanks John Wayne. based on your post, it's definitely a gen problem. I'm still confused though as to how the microwave was dead, I even plugged it into two separate outlets, then plugged another microwave into the same outlet to verify power, then tested the outlet with a volt meter and pulled 119v, so I know the outlet had power, but the microwave was dead, no lights on the screen/panel or nothing, then I plugged it into my garage about 2 hrs later and it came on and works like a charm.
