Running lights go out.

With enclosed trailer hooked up after a few miles i lose all RV running lights. turn signals and brake lights work. I can turn off lights and wait for circuit to cool down and turn back on. sometimes they stay on 5 mins, sometimes an hour. I feel like there is a ckt breaker thatbis too low in amperage or needs replaced. this trailer works fine on truck. open trailers work fine on RV.

I would be looking for a bare wire. I.m guessing a short in the trailer wiring.

I will start at trailer and inspect every wire and work my way forward to the 7 way. Thanks. But it only does it on RV not truck or jeep or FJ. Maybe they have larger amperage breakers than the RV. Appreciate your insight.
