I had a very similar problem in late summer doing what you describe .....the problem was a bare wire in the axle tub hitting the axle off and on and more on than off until no trailer brakes.
Same here. My old TT would have SH and OL on the Prodigy display intermittently. I found the OEM wiring on the trailer chassis was a mess with a bunch of crimp connectors on the daisy chained wires.
My solution was to install a brake + buss bar and run dedicated 12V and Neg. wires to each wheel. That gave me clean, solid connections and I never had another problem.
