Aircraft
The aircraft lost power soon after reaching cruise altitude of FL250. There was an undercast that was lighter and more broken towards the south. I executed a glide towards ZZZ where it looked like I could divert without needing to fly an instrument approach. I notified ATC and determined that the ceiling in ZZZ was 8;000 ft. I maintained best glide until I was in the immediate vicinity of ZZZ and could start seeing landmarks through the undercast. I descended in VMC conditions and executed a visual approach into ZZZ without incident.A local repair station determined that an induction hose has wiggled loose of the connection at the left intercooler which would result in loss of turbocharging and erratic induction air pressures that would lead to a loss of power at altitude. They reconnected the hose and ground tested the aircraft before returning it to service. I retrieved the aircraft after an extended runup test and flew it back to base uneventfully. The induction hose is located in an area of the engine compartment that would not be visible in the preflight.
