a 'random' loss of power may not actually have anything to do directly with your coach, but may be more of an electrical connection issue along the shore cord, main outlet's breaker you are plugged into, or a utility company issue. We've seen those several times here where we are plugged in, on a private site.

the Inverter kicks on, if you have it turned on, whenever it senses loss of 120v incoming power to the Main Panel, whether from Shore Power, or the Generator, since both enter thru the ATS(automatic transfer switch). Having a loose connection somewhere along the path can present itself at first as a 'nuisance' issue, but later as a real threat to something burning up along the way, such as a connection at the shore cord, especially those shore cords that attach directly to the side of the coach, with a 'twist lock' type connector.

I would investigate any and all wiring points to make sure every wire connection is absolutely TIGHT, without any shore power, of course, while doing so. Check the Shore Power's main breaker, the end of the shore cord, the ATS box, and even your own Main Panel, especially the breaker which provides the incoming power to the Inverter's pass thru, normally called a 'Inverter MAIN' or similar wording.
