It sounds like you have a wiring issue on the brake switch circuit and it is making intermittent contact and that explains why it works occasionally. Since the manual override lever still works the rest of the circuits seem to be good.
I would recommend you check the brake switch wire for any signs of a short such as exposed or cut wire and fix as necessary.
I attached an FAQ on brake controller troubleshooting for you to check out also.
