could be one of many things.....
but my guess is the engines getting worn
either this is a old bike or bought second hand these bikes are cheaply made the metal they use fro building them is rubbish your engine is worn im guessing
also cood be lack of fuel getting to the engine or the clutch getting burnt out first 2 to check is the engine and clutch
