During two recent trials my Evo 290 engine has just died in 4th gear. The first time it happened it was at a two lap event and the engine stopped twice on the same section under medium throttle . Once restarted continued the rest of the event fine although it sounded like lack of fuel. The second time was last weekend when attacking a long muddy section up hill in 4th gear under full throttle. Again once restarted with a little difficulty the bike ran fine for the rest of the event. I have my suspicions that it could be lack of fuel has anyone had the same problem and if so is there a fix?
