Thanks for the help. It does seem as though something is cutting the power since there is a short delay before the pump will turn back on (even manually). Never had a problem before with the pump itself. It has run everyday since the problem appeared yesterday. I double checked the electrical connections on the pump and at the switch.

Is the problem sudden, or did it happen after a period of no use?
