Is the fault happening in the same spot every time ? I believe it's your cigar switches. Either 77u top, or 77n bottom. Couple things if it's happening in the same spot of the hatch it could be your traveling cable going to those switches.
Is it flat traveling cable ?
Also could be the switch itself, as they get older those switches get sensitive you'll actually start picking up fish plate bolts with them and it will drive you crazy.
I'd do those two things travelers to the 77's or just change out the 77's . You want a good 3/8 away from the magnet to the switch.
