OK, here is the latest.
as you already know, I took the boat to the dealer last wednesday. To fix this problem, and to do a couple other maintenance items. They did a bunch of checking, found that the fuel pump was borderline. What they did to fix it was replace the pump with an '03 style pump (required some other hardware as well.) The '03 is a different make and apparently a much better pump. The dealer even took the boat for a spin pn saturday, to make sure that they didn't experience any problems. That gives me added confidence that I should not have any problems.
I am very happy to have a solid dealership near me in my new residence!
