Okay, here is how a GFCI works, it measures the current flow on the white and black wire and compares the 2 values, if the value is different by more than 6mA (0.06 amps) it will shut off the Circuit, because that current must be faulting to ground. Old GFCI receptacles had no self check circuitry in them and if they failed internally there was no indication until an accident or external test occured. New GFCI receptacles (sometimes labeled "smart lock") have an internal self check circuit and if they have an internal fault they will shut off.
So how old is the receptacle if it is newer than 2 or 3 years it might be a smart lock, and just need to be changed.
I would plug the pump into another GFCI (after checking all the wires for any damage or salt creep or moisture) and try that to see if it works.
Feel free to ask me any other questions.
