It sounds like a carb/fuel problem, happened me a few times before and i switched it off and back on again it was fine but last nite it happened and she sat for about 1hr/2 but was no good didnt go away had to tow her home. When your driving along she suddenly looses all power asive u took the foot of the throttle then straight away planted it again as if its not getting fuel or something and if you held a real steady rev on her it would do the same... anyone have this problem before? Taking it down to a mechanics around 11 but just wanting to see what im lookin at... had it out on a run there around a few back roads giving her death and it happened again Cheers
