It is strange. Out today same thing, it happened 3 times in a row. I go up to a hill do a nice catwalk, skis come down, sled shuts off with the yellow light flashing and the little bottle on the screen. I did nottice that the only time it didnt happen is if I dont let off the throttle all the way when she came down. All the rads are warm, I didnt chek the antifreeze yet but I will very soon.
