Aircraft
During climb out at approximately 15;000 feet the RH engine experienced an uncommanded power reduction. We leveled off at 16;000 feet and notified ATC that we would need to return. We contacted Dispatch via radio to tell them of the power event and that we would be returning. I took over flying duties and the First Officer began [performing] the required QRH checklists. During the descent the RH engine flamed out. At this point we declared an emergency with ATC and informed the flight attendants; but told them we would not be bracing the cabin. We landed and terminated the emergency once we exited the runway. Upon further reflection; we received at least 3 'Engine Oil' aural warnings which led me to believe the FADEC attempted to relight the engine twice with the engine flaming out each time. I elected to secure the engine at this point as I did not want the engine to relight at an inconvenient time and eliminate the distracting messages during approach. My guess is the PS3 sensor failed or was providing inaccurate data to the FADEC.
CRJ700 Captain experiences an uncommanded thrust reduction in the right engine during climb. During descent for return to the departure airport the engine flames out. Several automatic relights are allowed to occur before the engine is secured by the Captain and a single engine landing ensues.
