I had a similar problem and the dealership adjusted the dwell angle for free.The problem was cured for good! It cannot cost much if they did it for free and it is worth just asking. Hope this helps.

hi, it sounds like its your alternator. Get it checked at a garage. Most probably the alternator, this is not a big problem, can be brought for around 50 pounds.
