Narrative:
The experimental amateur-built aerobatic airplane impacted power lines during a forced landing following a loss of engine power. The pilot reported that after 1.8 hours of flight and 3 miles from his destination airport the 'engine stopped.' He stated that the fuel pressure gauge was indicating 'no pressure.' The pilot then turned on the fuel boost pump and ensured the mixture was rich, the throttle was full open, and the fuel selector was in the on position. He elected to make a forced landing to a field. During the emergency approach to the field, the engine 'began to run again;' however, it ran for only 30 to 45 seconds. The pilot then attempted a forced landing on a road, and the airplane impacted power lines, which the pilot stated that he 'never saw.' The FAA inspector reported that the main fuel tank contained approximately 4 gallons of fuel, and there was no header tank installed. Without a header tank, the airplane's unusable fuel while maneuvering is 5 gallons.

Probable Cause: The loss of engine power due to fuel starvation, as a result of fuel moving away from the fuel supply outlets during maneuvering with a low fuel level, and the pilot's failure to maintain clearance with the power lines during the ensuing forced landing.
