Have you checked the bulb? Have you checked the socket? I have seen the sockets get wear and the bulb want stay in place. I've seen the bulb tabs fall off and not work. Check all the easy stuff first. Have you done any work on any of the electrical system latey?
Your brake lights and turn signals all go through the wiring harness in the steering column. Could be a wire issue outer sleeve worn through touching metal are a turn signal cam problem. Could be the bulb itself even. I'd start at the column harness connector and probe the wires that go to the rear of the truck with it in the position that gives you the problem and probe the wires and see if it does the same there if not keep moving towards the back of the truck and see where it starts being a problem.
