the 'rarely' part is going to make this the hardest thing to troubleshoot.
i would start with unplugging the passenger door harness inside the kick panel. that would eliminate any modules, switches, and wiring that's in the door that could cause issues.
then run it that way for a while and see if the issue keeps happening.
