Narrative:

While performing a functional check flight to validate performance of the GPS with the use of the night scanner landing light and verify autorotation RPM speed; the engine failed during the execution of the autorotation RPM speed check. No prior maintenance was performed on the power plant or flight control system.upon entry into the autorotation and confirmation that systems were normal; the throttle was reduced to the idle position for the check. The caution/warning system alerted me to the engine out condition and I confirmed the condition with the N1 and turbine outlet temperature gauges. An autorotation landing was performed to runway xx at ZZZ with no damage to aircraft or facilities.
