1. Check to make sure that all plugs and sockets are snug-fitting (Good contact) and plug pins are straight and clean. Try wiggling each connection right after you plug in and see if that gives you power.
2. If you have a generator, you may have a problem at the transfer switch.
3. With power unplugged, open up your RV circuit breaker box and make sure that the screws at the breakers are all tight. Also, check the screws at the power connectors on both ends.
