Use a meter and check the power at the pedestal. Also check at the coach end of your shore cord. If you have a cord reel you might need to bump it in or out a little to possibly get the contacts in a better position to pass the power thru. The pedestal breaker or your 50 amp main might have tripped. Reset and see it that makes a difference. If you have a transfer switch check the lugs there for power also. Could be a combination of things.
