Probable Cause
the builder/pilot's improper modification of wing fuel caps resulting in the failure of the vent system to adequately compensate for the pressure differential between the fuel tank and the external low pressure area of the wing. This led to the partial loss of engine power in cruise flight due to fuel starvation, and a forced landing.
