ShurFlo 5.7
Test the voltage as close to the pump as possible. The idea is that
the voltage should drop a little when the pump runs. This means the
pump is drawing power, as it should.

If the voltage goes up as the pump stops, then the pump itself has
stopped drawing power meaning the internal pump controller is
responsible for the stoppage.

If the voltage goes way down or off as the pump stops, then the problem
is with the bus's supply of power to the pump. This could be a breaker
going off and then auto-resetting. Also, there could be a pressure
control device installed by BB that interrupts the power to the pump.
Finally, a bad connection might suddenly show up with a new pump that
draws more power. This could be a hard one to find, but it is also
less likely.
