Almond151 my bike has the exact same symptoms as yours and with a brand new battery, I think Andy might be onto something with the regulator/rectifier, thanks Andy for your advice, my bike's been like this since i got it so i didn't know whether it was a gradual or sudden problem, but with Almond151's bike doing it suddenly, it rules out any alternator/magneto problems because from experience, they die slowly, not all of a sudden. PROBLEM RECTIFIED.
