Question

Answer
The high mount light is controlled by a different switch.
The regular stop lights use the same bulb as the turn signal. The signal control carries the power to the stop lights, so a loose connection in it could cause your problem.

I would make sure the signal flasher is in good shape first, but I think in the signal switch is where your problem is.
