Tech help needed

[RCP57]

It almost sounds to me like the ESC's have lost their programing. I had a Hobby King ESC on the pump in my excavator temporarily and it would do this once and a while. I would plug in the battery and it would go into programming mode and just sit there and beep. If I touched a function the servos would move the valves and the tracks would work but no pump. Sometimes, if I unplugged the battery, plugged it back in and waited a bit before touching anything on the TX it would stop beeping and work properly. I tossed it and bought a good ESC(Jeti spin 33) and now have no problems.
