Approximately 5 to 10 minutes after level out at FL410; the left engine flamed out while at a long range fuel setting and at mach .67 or .68 for maximum range. I requested FL250 from ATC and was cleared to FL250 and ATC asked if I had an emergency. I informed ATC that I had experienced an engine flameout and was going to descend for a restart. ATC asked again if I was declaring an emergency and I replied 'No; I am descending for a restart'. On reaching FL250; I completed a windmilling restart according to the checklist at which time the engine restarted normally and came up to power. Since the flameout was most likely the result of high altitude and low power settings and the engine was performing normally; I requested and climbed to FL330 and monitored all engine settings which remained normal. After landing; I had a Mechanic look at the engine and complete a normal start and power run and will have a logbook entry that the engine is airworthy.
LJ25 Captain experiences an engine flame out at FL410 which is attributed to the high altitude and low power setting. A descent to FL250 is requested and the engine is successfully started. Flight continues at FL330 and upon landing Maintenance can find no faults.
