Confidence Rating: Accident investigation report completed and information captured
The pilot reported that, after about 30 minutes in cruise flight, the engine began to run roughly, followed by a loss of power. The pilot attempted to restart the engine twice but was unsuccessful. He then initiated an emergency landing on a dirt road. During the landing roll, the left wing struck an irrigation pipe, which resulted in the airplane departing the road and coming to rest in a field. 
A postaccident engine examination revealed that the engine was modified with an Ellison throttle body under an experimental, amateur-built airworthiness certificate. Attempts to run the engine with the Ellison throttle body installed were unsuccessful. Once the throttle body was removed, the engine successfully started. An examination and teardown of the throttle body did not reveal any anomalies that would have caused the throttle body to malfunction.

Probable Cause: A loss of engine power for reasons that could not be determined because postaccident examination of the throttle body revealed no anomalies that would have precluded normal operation.
