Narrative:

Departed on an IFR flight plan north with 4 passengers on board. At flight level 250 I requested lower and was given descend to flight level 240. I powered back for the descent and at 24;000 feet powered back up using primary torque/throttle control for level flight and did not get a response as I continued to descend. I brought power to close and repowered and did not get a response and pulled nose up to maintain altitude. At that point I got a gear down aural message that led me to believe I had lost the engine. I notified ATC that I had an engine failure and wanted vectors to the nearest airport. After getting established on a course to ZZZ while descending I activated the secondary power control lever and the power came back. I informed ATC that I had recovered power and continued to a safe landing at ZZZ.
