A few months ago, both outlets stopped working at the same time.
I thought one of them would be feeding another one. So I bought two GFCI outlets to replace both of them in case. When I opened the outlet and tried to find which wire is line and which is load, it seemed like neither has power in them in either of the outlets. They both have four cables with white and black wires in them. So two of them should be line and two should be load (at least that is what my understanding is).
Could it be that it is getting load from somewhere else and that is where the problem is?
