RE: keeps jumping off
I would review the breaker schematic to see what relaying is connected to the trip coil. Make sure all relay targets are reset.
Is this a recent occurence? Have the relays been calibrated recently?

Check that generator against others if you have mor than two.
Check that quadrature droop CT is in correct phase in each and check that polarity is correct.
