Self Serv. Bay issue

I would look for an air leak on the inlet side of the pump. With the pump off start at the inlet of the pump and look for even the tiniest of water leaks. It can also be the seals of the pump itself if you find no leaks in hoses or fittings. This usually presents itself as dripping water from under the pump. Hope this helps.
 
It could almost anything. Is the motor in the equipment room starting and stopping? Have you checked the wiring in the coin box for any loose or damaged wires? Rotary switch could be bad. Check the wiring on the pump skid for loose wires, primarily on the rinse side.
 
I would check for:
* a slipping belt
* a weak/dying electric motor
* a loose pulley
* air leak on intake side, including a low chemical or too high pick up tube
* everything Randy said.
