Beaver Marquis Bose Replacement

A side question here - off to the right side of this cabinet in my Beaver are two wall outlets one on top of the other? I wonder if yours is the same. The reason I am interested is that while testing my audio system I had the sound bar and subwoofer plugged into the top outlet set, and while playing the music I was testing my rear view camera. To test the camera I had to turn the ignition key on (generator was running this whole time to provide power) and when I did this, that outlet cut out. The one below it was still hot, but that one cut out. I didn't look too closely but it appeared that both outlets were on the same loop of wire so it didn't make sense that one went out and the other stayed hot. When I switched the key off, the power to the top outlet returned, so I wondered if you knew why. Looks like I'll have to plug in the TV, Sound Bar, subwoofer, satellite tuner and Satellite controller to the bottom outlet.
