Sigh I have a similar problem. I bought my gilera coguar second hand less than a week ago, fully mot, but every time I ride it, it suddenly loses all power. I have been trying to identify what causes it. Usually I have been riding 10 mins at least before the problem occurs and I think maybe I am usually in 3rd gear. Sometimes, I can be riding straight at a constant speed and it loses all power. I am a first time rider so I am a bit lost, not to mention disappointed at the failure of my shiny new bike.
i have the same problem, changed both the coil and the plugs, also the gasket, still no improvement, i think its the exhaust, not losing the spent gas quixck enough as mine sometimes backfires and springs back into life
