At about 1315 Mountain time, the airplane made a forced landing following a loss of engine power. The Private pilot and single passenger were not injured; the airplane was substantially damaged. Visual conditions prevailed; an IFR flight plan had been filed. The pilot reported the airplane was cruising at FL260 when the engine quit and he saw smoke coming out of the exhaust. He performed an emergency descent to 15,000 feet, and at 12,500 feet attempted an engine restart, which was unsuccessful. He proceeded to the nearest airport and performed a no-power landing. After touchdown, the airplane continued down the runway, off the end, and into terrain and a fence.
