Aircraft
My student and I left for a local instructional flight from ZZZ; which I expected to last for about an hour and a half. We departed toward the southeast and we did some maneuvers. We then did a practice diversion to ZZZ1; did a landing; and departed to the northwest. When we were about 15 miles away from ZZZ1; I had the student descend to 1300 MSL; about 800 AGL; for turns around a point. During the maneuver; the engine stopped running and we could only get it to run at idle. I took flight controls and pointed us toward a field and my student checked mixture; verified fuel pump was on; cycled the magnetos; and turned the prime on. On our final approach to the field; I extended the flaps to landing (fully extended) and then we slowed to 60 on final approach. My student secured the engine by pulling the mixture to idle; closing the fuel shut off valve; turning off the magnetos; and also turned off the aircraft electrical system. The aircraft touched down and we brought the aircraft to a stop in the field and then I called our flight dispatcher. The problem is believed to be an issue with the aircraft's fuel system.
Reporter stated that post maintenance inspection revealed a fuel line clip had come loose which caused a fuel line to vibrate and fail.
