The fact that you have regained function of the circuit after mentioning the high temperature in your first post, tells me that a neutral connection in a wire nut, is loose. Check connections in attic, if any, when it is bearable to go into attic, or connections on that circuit on your "hot" wall, (a wall that is getting a lot of sun).
Mining equipment is run on 3 phase w/ground cable, carrying 995V or 480V. These cables lie in the mine floor and are occasionally damaged, and sometimes may be in mud or water. It is/was standard practice to touch the back of a cable with the back of your hand to prevent the stray current to cause your hand to lock your grip on the cable. It was mandatory to wear gloves, but the back of the hand procedure saved me and several of my employees hundreds of times.
