Thetford C2?

Probable a bad connection on a terminal block in the wiring to the toilet I take it you've tested the current to pump when depressing the flush switch? Another camper had same prob his dropped to 4volts and what he found behind the bathroom panel a bad block joint re-did joint all ok.
