When this happens it means the stoplight circuit is shorting out to the brake output circuit. I bet if you turned on your blinkers one side would cause the brakes to intermittently lock up too.
What you need to do is go over the wiring of the trailer and vehicle (starting with the connectors) and look for any obvious signs of a short and fix as needed.
