I had the same problem with mine. Just bought it a few days ago, went in it to go get my tags, and it turns but it wont ignite. I jumped it off to see if it was the battery, at first it wasn't starting up then finally got it to fire up. So then I figured it was just the battery. Well I let it run for a good solid 10-15 min to make sure the alternator charges the battery enough. I cut it off, not even a minute later I go to crank it back up to see if it was good to go, started up, them the RPM just went to 0 and cut off. Then it wouldn't even try to ignite after that; Jumped it off yet again and let it run some more. As of right now it seems to be doing decent after hours of working/ trying to figure out wtf is wrong. Stopped messing with it cause of the rain, so tomorrow I'll see if it cranks right up.
