Narrative:
A student and I were practicing stalls for private license. He did pattern traffic work for 30 minutes then we headed to the north proving grounds; we did 4 maneuvers in total at 4500 feet. Steep turns; slow flight; power on and as we were doing power off stall on the recovery procedures; the engine was running rough and started wind milling and stop; so I took control heading back to the airport while taking care of the trouble shoot checklist; the engine came back. We were on our way to the airport; as I communicated we had had an engine failure and we will like a straight in approach. ATC gave us priority and as I had altitude and my engine back; we made it back safely. I work for a flight school and was not sure what the problem was; I believe as my student was adjusting power with excessive corrections he was too aggressive with throttle which could have cause a failure of a spark plug. Happy that we made it back safely; it was definitely an intense and concerning experience.
