I've got a new DA50 in an Extra 260 and the engine runs for about 2 minutes and then cuts.

It had a total of 10 minutes running time now and every time it dies close to 120 sec into the flight.

The prop spins when the plane is coming down, so it seems that there is NO compression. The compression does return as the engine cools down.

Whats the best way to fix this. Has anybody else heard of this problem before?
