There is a vacuum dump switch actuated by the brake pedal (look under the dash where the brake pedal lever is) that opens the vacuum circuit to the atmosphere in order to disconnect the cruise whilst braking. It is a common failure item which will keep the cruise fom engaging. It may also just be out of adjustment, you can thread it in and out to do so. Barring that, it may be loose contacts (you said it works intermittently?) or a control box problem (find a used one).
