During cruise flight at 41;000 feet I experienced an engine failure. Initially the failure manifested itself with a fuel boost pump failure and associated popped circuit breaker. Immediately thereafter; the engine flamed out and rolled back. We declared an emergency; obtained a lower altitude and clearance into a nearby airport. We worked through all appropriate checklists and performed an uneventful single engine landing. Having flown Part 121 in the past; the training gained there was extremely helpful in handling the situation. In working with Contract Maintenance; and several manufacturers; a bad engine driven fuel pump was identified and changed as a result. Freezing fuel was a second considered possibility. Since fuel contamination was considered a possibility I contacted the last vendor we purchased fuel from. They quarantined their truck; sumped it; contacted other clients who took fuel from the same truck and advised them. The fuel samples were clear and no adverse reports were received from other customers.
A Falcon F20 engine flamed out at FL410 after the engine driven fuel pump failed. An emergency was declared and the flight diverted to a nearby airport.
