Last week my nephew hit my well head it severd a power line I didn't notice the split due to it was in a splice . When I discovered it my water pressure was low now that I fixed the power I still have low pressure my switch will turn on for about ten seconds then off for about two min. Then back on . I still have low presure
Sounds like the pump is going into thermal overload. Either you wired it back up wrong or it damaged the control box.
