Just had that same type of thing happen at work this week. A heating element quit working. Continuity across it appeared correct but it didn't heat up. Turns out what it was, was a broken wire, it was stranded and was only hanging by a few strands. When I turned power off and started jiggling wires the wire broke away by the element connection.
So I would say look for a poor connection. Might be the outlet, might be the breaker, might be a wire, could be a wire nut. Outlets are notorious for burning up. Look for carbonizing on it, that is a clue.

Electrical socket that has worked for the better of 7 years mysteriously quits working. 20A duplex socket used for gas convection oven and also to power incand. over the sink light.
Basement is finished but from what I can determine wire goes right back to breaker box from duplex outlet. I can measure 120 VAC at outlet but shop light will not work when plugged in.
I unhooked the wires in the breaker box and also at the duplex outlet and checked for a complete circuit with positive results. I can not find a short to ground when testing the wires.
Anyone have an idea of what is happening?
