OK, I have a Ski Nautique that has a small problem. It will run for a while (1-2 minutes), then all of a sudden bog down and die from gas starvation. I have gone through the fuel lines, checked them for clogs/leaks, and none were found. I put in a new fuel pump and fuel filter, and it still dies. I have even totally rebuilt the carbeurator and it still dies. Now the funny thing is, the motor will run all day out of gear and while level. When you put it in gear is when it will run for a little bit and die. I thought that maybe the vent in the gas tank was stopped up but when I tried to run it without the gas cap on it still didn't work. If anyone knows what problem this might be and what I need to do to fix it, I would greatly appreciate it.
Thanks in advance.
