I have a 2001 Scram 500 2X4, and the electric start on it is acting funny. When I go to pull it out of my garage, it starts right up, but I'll only have it running for a few minutes pulling it to my back yard, then shut it off. But if I go to start it up lets say 15 minutes later, it sometimes wont start at all electric start, no noise nothing, or it will start but sounds as if its ready to die, until I give a lil gas and then it idles fine and runs fine. Whats the deal?
