I can't speak for your model specifically but in ours, every outlet (with the exception of the microwave) are daisy chained on one circuit. The bathroom is first in the chain with the only GFCI outlet. If that trips, they all lose power. In my case, I found a short in the very last outlet before a long trip so I was able to disconnect that one and that fixed the issue for the trip.
Assuming you really have only one GFCI outlet, I would assume they are all on the same circuit. Since the GFCI is not tripping, I would assume there isn't a short anywhere in the circuit. Perhaps then, somewhere along the chain, the wires slipped out the "clamp" on the back of an outlet which removed power from all the downstream outlets in the chain. I suggest pulling each outlet to check and see how well the wires are seated into the "clamps". Also check for any scoring/melting on the back of the outlet. At the same time, you can map out the order of the outlets so you have it for future reference. Good luck!
