Went to a trailer repair shop. Installed new break away switcch. Brakes are working fine now.I will check each individual wheel when I get home and check for good ground and chafed wires.
Hopefully that fixes it.
Makes sense, breakaway switches are heavily exposed to weather and it is possible with heavy soaking rain can get past the rubber oring and fill up the switch cavity with water.. Water sloshes as you drive and makes good enough connection to short the two contact fingers inside the switch which allows full battery voltage to be applied to brakes..
Sort of surprised that did not lock and slide the wheels on you though..
