Disconnect the motor leads from the GFCI (all 3 of them), then use an
ohmmeter to check for leakage between the ground and neutral. Use the
highest scale you've got ... IMO anything less than a megohm (1,000,000
ohms) is suspect.
If the resistance is low, you can try disconnecting the wires at the motor
and testing again on the motor terminals ... but my guess is that it will be
the motor itself. If the housing is grungy, might be worth cleaning it and
trying again, some mud can be pretty conductive.
