Narrative:

On date; on a flight from ZZZ; to ZZZ1; on aircraft X; at a cruise altitude of 4;500 ft.; I experienced a loss of power to the right engine. With directional control established; and with the aid of the checklist; I attempted to troubleshoot the reason for the power loss. An IFR clearance was obtained from ATC due to decreasing VFR conditions; and ATC advised of the problem. A decision was made to shut down the right engine; feather the propeller; and [priority handling] requested with ATC. With good single engine performance; I evaluated my divert options. Given the weather conditions and my familiarity with the airport; I determined that ZZZ1 was my safest divert option. Clearance was given to ZZZ; where an uneventful approach and landing was accomplished. Aircraft is currently under maintenance to determine the cause of the power loss.
