I'm wondering if your fuel valve is contributing to your problem, although I'm not sure why. If I remember correctly, the dual tank fuel valve has some type of vented tube. I don't believe the gas caps are vented.

One other thing, if your valve is leaking from the seam, you may start experiencing a stalled engine especially if you rev the engine like on the highway climb. It seems almost like a fuel pump going out. I'm guessing that the stalling occurs because the fuel pump is pulling in air from the valve leak instead of fuel.

BTW, are all the fuel/vent lines plumb into the valve correctly?
