Narrative:
I turned 10 mi due north of the airport (sundance) for a straight-in approach. I had monitored ATIS of a nearby airport and knew all relevant WX factors. I switched fuel tanks after my turn. I started my descent to pattern altitude. I notified airport traffic of my intentions immediately after my turn in (10 mi). I continued to talk to and monitor traffic. Traffic was very light and I heard no communications from other traffic. At about 7 mi. I developed a loss of power. I radioed a mayday and went through an abbreviated emergency engine restart. Due to my altitude, I started searching for a place to set down. I was losing altitude quickly so I set down in a wheat field 4 mi north of the airport. During this period, I was also in contact with sundance unicom who heard my mayday.

Narrative: I TURNED 10 MI DUE N OF THE ARPT (SUNDANCE) FOR A STRAIGHT-IN APCH. I HAD MONITORED ATIS OF A NEARBY ARPT AND KNEW ALL RELEVANT WX FACTORS. I SWITCHED FUEL TANKS AFTER MY TURN. I STARTED MY DSCNT TO PATTERN ALT. I NOTIFIED ARPT TFC OF MY INTENTIONS IMMEDIATELY AFTER MY TURN IN (10 MI). I CONTINUED TO TALK TO AND MONITOR TFC. TFC WAS VERY LIGHT AND I HEARD NO COMS FROM OTHER TFC. AT ABOUT 7 MI. I DEVELOPED A LOSS OF PWR. I RADIOED A MAYDAY AND WENT THROUGH AN ABBREVIATED EMER ENG RESTART. DUE TO MY ALT, I STARTED SEARCHING FOR A PLACE TO SET DOWN. I WAS LOSING ALT QUICKLY SO I SET DOWN IN A WHEAT FIELD 4 MI N OF THE ARPT. DURING THIS PERIOD, I WAS ALSO IN CONTACT WITH SUNDANCE UNICOM WHO HEARD MY MAYDAY.
