Flew from KLZZ to KSEP for BBQ at Hard Eight. On the initial takeoff roll had a power failure and engine stall immediately. Runup was fine right before that. Called the factory who explained it was likely vapor lock, it occurs in Rotax engines occasionally when using auto gas. There are many regional variations to auto gas, and if you use fuel from a cold region on a day when it's hot, combined with a long idle on the taxiway, the hot engine can cause the fuel can vaporize before it detonates in the engine, causing power failure. The solution was to shut down the engine and let it cool for 30 minutes, and it ran fine after that. It doesn't happen in the air because you have air and water cooling when moving, but on the ground the water cooling can sometimes be ineffective. We were ready to call it a day but my discussion with the factory convinced me to try it again.
