Most likely the problem is corrosion in your trailer connector. Dirty pins in a connector are notorious for causing intermittent circuit function which is exactly what is going on with your setup. Corrosion can also cause shorts too.
Aside from that it could be a loose wire on the brake output circuit somewhere, but it sounds like you already checked that.
