Helicopter instructor experiences a low boost light climbing through 8;000 feet followed by an engine failure at 10;000 feet. An autorotation is performed to the nearest airport; where the fuel cap is found to be loose and then tightened. The aircraft starts normally and is flown to a nearby airport for fuel then back to base.

Narrative:
The 'low boost' light illuminated climbing through 8;000 MSL. All other engine instruments were normal. Experienced an engine failure at 10;000 MSL. Unable to air restart after multiple attempts. Performed safe auto-rotation. Once on the ground I discovered the left fuel tank cap was loose. After tightening the fuel cap the aircraft restarted normally. After departing ZZZ; flew directly to ZZZ to add fuel and then direct to ZZZ. The instruments and flight were normal on return flight.
