Narrative:

My student was in the traffic pattern to practice power off 180's. It was around 108 degrees fahrenheit. He moved the throttle to idle; the prop continued to windmill so the exact point of engine loss is unknown. When we reached the runway; the student was going to land short of his point so he attempted to go around. At this point the engine did not respond. We were already over the runway; so the student safely landed the aircraft. We then informed tower that we lost our engine; but would be able to safely exit the runway to attempt to restart and taxi to the ramp. After several attempts; we were finally able to get the engine restarted and taxied safely back to the ramp.
