All good advice so far. Remember, GFCI's don't trip on overload, only on ground fault, so don't rely on the GFCI to do the work of the breaker. Your space heater probably maxed out the circuit by itself, and if it was tied in conjunction with other appliances it most likely burned the receptacle.

GFCI receptacles don't trip on overload. GFCI breakers are designed to trip with overload. Maybe I should have made it clearer. Sorry.

Yeah, the breaker will trip on overload by design. The GFCI only trips on ground fault, not overload. It may burn up before it trips the breaker, but it's not its job.

It is possible your trailer or one of the tools has a fault that you don't know about, and is tripping the GFCI.
