Well, fuel lines, old or leaking or not will not cause the symptom he's
having.
Next, the nature of the double relay is more less 'yes or no' .........I
believe.
It provides, as the poster realizes, power to the fuel pump, and to the
brain.
Why it's in one relay is a mystery.
Subsequent vanagon fuel systems have two individual separate relays, which
is only logical.
I don't think I would call it flooding quite, I might call it 'running full
rich' - or that's what I suspect, but more info would help. .
Or I would suspect that's what might be going on to make it run only at WOT.
I'd consider the tenp sensor that talks the ecu. Screwed into the left head
I believe.
They can get corrosion there, and cause weirdness.
Subsequent models of vanagon fuel injection have two wires for this
function, rather than depend on the engine metal for a return path.
Also grounds , there are push-on ground connectors hidden under the intake
manifold that get weak - a real vw joke. ALWAYS re-do, clean,
tighten, etc. all grounds for EFI weirdnesses.
I happen to have a used double relay for a non-california air cooled
vanagon, btw.
It 'might' be ok-ish.
Dig into the checks in the Bentley manual more.

Although a hackneyed topic (for good reason!) you might consider replacing
the rubber FI lines into and in the engine bay. (use properly rated FI hose)
Even though it hasn't been run much, the lines might deteriorate from time.
It may even be that one is leaking though from the sounds of things, you
would likely have noticed. I imagine the leak would have to be quite bad to
stall out the engine. Regardless......
Not a hard job, and worth piece of mind.
Neil.
