Mine was doing something similar... turned out to be the battery terminals (diagnosed by checking voltage at the battery terminal and then on the other side of the terminal clamp... nearly a 5 volt differential). A couple of minutes spent using the terminal brush on the clamps and posts and everything was golden. I hope yours is fixed as easily <img src="/forums/images/graemlins/kewl.gif" alt="" />
