Bringing to life this old thread. My VX has done this 3 times now. Always after it's warmed up, not necessarily in any one kind of weather, no lights, always starts right up, no modifications have been done to the VX. It always dies when rolling to or sitting at a light. I am going to do some routine maintenance to make sure its nothing like that. New air filter, new fuel filter, plugs, fluids ect, getting ready for winter anyway. Hopefully that will solve it. Has anybody figured out why theirs died?
