The aircraft was being ferried to the new owner when the accident occurred on the third leg of a flight from Hartford, CT to Dallas, TX. The pilot reported that the fuel tanks were full when he took off at 2020 EDT. He proceeded en route at 4000 ft MSL at a groundspeed of about 96 kts. The pilot stated the fuel mixture was leaned for the flight. About 35 miles from the destination he noticed one fuel quantity gauge indicated near empty, and the second gauge indicated less than half-full. About 10 miles out both gauges indicated near empty. Soon afterwards the engine lost power, but he restarted the engine. However the engine lost power again and he made a forced landing in a field about a mile NE of Lex. About 4 ozs of fuel was drained from the fuel system during the post-accident examination. Fuel consumption calculations indicate about 5 gals of fuel should have remained when the power lost occurred.
