Outlet with a mind of its own!

Hello All.
I have a weird situation. There is a GFCI outlet that powers my microwave. When I use the microwave, sometimes the power cuts off and it also cuts off power to my fridge (on a separate outlet). I wait about 10 minutes and the power comes back on its own. During this 10 minute wait, if I plug in the microwave, it will get power in bursts causing the microwave to beep on and off. After the 10 minute wait, I plug in the microwave and get one beep letting me know the microwave is "booting up" and it's good to go. I thought maybe the microwave was bad but as I mentioned, the fridge also gets cut off. What gives? Ghost in the outlet? anyh help is appreciated.

Thanks

Is this a multi wire circuit? That is does either of the two breakers involved have a red wire on it.

Nope. no red wire. At least non that I can see. But, for argument sake, what would your thoughts on it? By the way only the outlet behind me microwave is a GFCI. the fridge is not.

This is probably a loose or weak connection somewhere in the circuit that is overheating and coming apart. When it cools, the connection re-establishes and power comes back on. The fix is to box-by-box on this circuit, remake connections solidly, convert back stab wires in receptacles to screw terminals, and replace anything that looks burned or heat damaged.

Maybe I misread:
also cuts off power to my fridge (on a separate outlet).
Is the refrigerator on the same breaker? I read that as a different breaker. If on the same breaker ignore my response. Ben's instructions are better in either case.

Receptacles

Sounds like the microwave GFCI is upstream of the fridge receptacle.

I had a similar problem once. I replaced the GFCI and the problem went away.
