Narrative:

At FL380 shortly after reaching the top of climb; I made an airspeed adjustment to conserve our fuel burn. At the top of climb we were at an airspeed of mach .76 so I elected to adjust the airspeed back to mach .72 in order to see where my fuel status would be upon arrival. We were running behind schedule; therefore I elected to resume the airspeed back to mach .76 for cruise; as I was satisfied with our landing fuel status. As the aircraft was increasing in airspeed to mach .76 from mach .72; I noticed an itt (inter-stage turbine temperature) exceedance on the left engine. Shortly thereafter the itt exceedance the left engine rolled back to a failed engine status. I immediately [advised ATC] and began a shallow descent to FL240 while turning to the nearest suitable airport. During the descent phase and while running the qrc; the left engine auto relighted. Leveling off at FL240; I slowly advanced the thrust levers to increase our airspeed; and at that point the itt on the left engine went back into an exceedance status and shortly thereafter the left engine failed again. We were then given a clearance to descend to 4;000 ft heading directly to ZZZ. During the descent phase the left engine auto relighted again. At ZZZ I elected to enter a holding pattern over the airport using 10 mile legs to accomplish a thorough briefing of our approach with my crew along with accomplishing all required checklist and procedures. The approach and landing was accomplished with both engines running using normal landing procedures. We landed safely without any further incident and the passengers deplaned the aircraft safely. Prior to this flight; the aircraft was received from the maintenance hangar. The left engine was a replacement engine.
