Check your mech fuel pump. Mine just went out due to a faulty (worn) actuator arm. My boat is a '96 with a 502 MAG running the VST and I thought the problem was in that vapor tank, but turned out the mech fuel pump was the issue. It was doing the same thing- died then sputterred. Also was sputtering in the top rpms before which led me to clean the VST thinking it was f-ed.
Check my post in the "Do it Yourself" section of the Technical Forums. I got some pretty good info. Good luck.

Here's the port. Seems to be less water down there than yesterday. Going to siphon it out now and try to clean all the electrical connections down there and inspect the pickups.
Picked up new fuel filters as well. I'll keep the thread updated as I progress today.

Sounds like the problem is in fuel starvation, since you said the line had no fuel leaking out of it when you took it off. Are you "sure" that there's no water in the fuel??? That will make the difference of it not running when it has fuel pressure.

Bypass the main tank and use a small doner tank small fuel, bottle etc, be carefull as not to spill fuel. if it starts and runs on the doner tank its got to be in the pickups in the main tank. My motors vaper lock on early season fuel but it usalley happens when hot and hatch closed after running hard for 15 miles or so.... my bet it is in the pickups or water in fuel

Check the vent on the fuel tank on the side of the boat. Spiders make nests in there and that will cause you problems also. Usually just when you go to fill, but i have seen motors starve for fuel because of a clogged vent also.
