Hi all, new guy here. I just bought a 2007 gti se 155 with 21hrs on it. The last owner had the 15hr service done last year. Then rode it for about 5 hours. This was 10 months ago. Didn't have much fuel, but he did put stabil in it. Took it out this past weekend after filling the tank up. All was fine for a couple of hours off and on. Then all of a sudden, it would just die. The fuel gauge showed 3/4 tank. I would start just fine and idle for a little bit, and then die again. Saw the 12v low light come on. Brought it in and saw the + cable really loose. Tightened it up and thought we fixed it. Next day topped of fuel and same thing happened when it got to 3/4 tank. Took it home and decided to try some spark plugs. Took it out the next day, but this time I didn't top it off with fuel. Idled for a couple minutes in the no wake zone then got on it. This time it lasted for about 1 minute. Then it died again. It would start again and idle for about 30 seconds, then die again. What is happening at 3/4 tank of fuel? We brought up fuel venting, or a lack there of, but have not checked the cap yet. What else could it be? Any help would be greratly appreciated. Jerry.
