Narrative:

While at FL410 after being airborne for approximately 45-55 minutes; we felt a 'pop/boom' accompanied by a left yaw followed immediately with indications that the left engine had failed. Specifically; there was no fuel flow and the N2 reading was zero. There were no abnormal indications before the failure occurred. All readings were normal. We then performed the engine shutdown or failure in flight checklist followed by the one engine inoperative approach and landing checklist. We declared an emergency and asked for clearance to an airport with long runways/facilities which would be suitable for an emergency aircraft. We were cleared to a nearby airport and arrived at the airport at approximately 20;000 feet. We spiraled down and the approach and landing were uneventful.
