Check to see if the 3rd (high mount) brake light continues to work when the lower 2 don't. If so, you have a bad turn signal/combination switch in the steering column. The lower 2 lights "only" pass through that switch.

Then you have a problem with the brake light switch, the power to it or the wiring in between, assuming the bulb isn't burnt out of the 3rd light.
