The airplane impacted the terrain in a field following a loss of engine power on takeoff. The pilot reported the engine start and run up were normal. He stated that the engine quit and restarted when they were about half way down the runway during the takeoff. He stated this occurred again when they were too far down the runway to abort the takeoff. The pilot reported there were high-tension lines in front of them so he descended to fly under the lines. He then saw lower power lines near the road. He was able to fly above these lines. The pilot reported that the engine power continued going on and off during this period. The pilot reported the airplane was about tree top height when he banked to the left and then to the right to line up with a field. It was during this time the airplane stalled and impacted the ground. Inspectors from the Federal Aviation Administration Flight Standards District Office in Belleville, Michigan examined the airplane and engine. The inspectors reported the magnetos produced spark and thumb compression was achieved on all the cylinders. The carburetor was inspected and it was determined that approximately one third of the fuel screen was plugged by dirt. No other mechanical failures/malfunctions were identified. The pilot's last medical certificate was a Third Class medical dated April 2, 1999.
