Ghost in the Front Roof

Hi all. I have an interesting problem with the front roof electrical. It is a 2002 2720SL. We are camping now for the weekend with our Grandson. Last night at 8:00pm we were sitting on the sofa watching tv when all electrical on the front roof went out. lights, fan, porch light, everything. I checked the 15amp fuse in the breaker box and it was fine. I planned to start a chase today by the light of day. This morning at 5:00am the lights suddenly came back on. I am dumbfounded. I am thinking either I have a ghost or maybe a loose ground somewhere? Anyone have any thoughts on this?
