The pilot had been flying the airplane the previous week with no discrepancies noted with the airplane or engine. He had flown into the airport the day before the accident and had to refuel the airplane with auto fuel because the airport did not provide aviation fuel. The pilot stated that the airplane had been approved to use auto fuel by an STC. The next morning he conducted a run-up with no discrepancies noted. He stated that the takeoff was normal, but at the departure end of the runway the engine stopped. The engine did not sputter or cough, but the rpm's dropped and the engine became quiet. The pilot turned the airplane to the left and made an unsuccessful attempt to restart the engine. Witness to the accident stated that the airplane appeared to be at full power, but airspeed was low and the airplane was not climbing. Following recovery of the airplane, grade 100LL aviation gasoline was put into a tank and plumbed into the airplane fuel system. During the first attempt to start the engine, it ran rough. A second engine run was conducted with no discrepancies noted. The engine was examined with no discrepancies noted.
