I had the same problem. I swapped two of the same relays for the stop lamps under the hood in the fuse box panel. The problem went away. Apparently the relays stick some time.

Some of these had two fuses for brake lights. One for the top/center stop lamp and another for the rear left and right brake lights. Usually one said "stop" and the other said "brake" and one was in the underhood panel while the other was in the dash fuse panel. It's not uncommon to blow a brake light fuse [LR and RR] if you tow a trailer but some of these had seperate fuses for the trailer lights also. If you have a test light check both sides of the two fuses for power [ignition key on] while stepping on the brakes. It should at lest narrow your search a bit.
