I dont believe the lift pump would do that. The VE has the capability of drawing its own fuel, just makes it a dog. Possibly the governer spring, but I suppose Id be more inclined to believe the IP is on its way out. I'll ask some folks n see what I come up with for you.

OK, I got with a friend of mine that knows much more then i do. It could be a clogged fuel filter, or bad lift pump. Does it start generaly easy? It could possibly be air in the lines as well. Just basically isnt getting fuel.
Try some of these, replace filter, install fuel pressure guage, put in a section of clear hose in the fuel line. (the closer to the IP the better) I dont know how to really test the lift pump, but I would assume you could pull the outlet, and use the manual prime lever and see if it is putting anything out. If that ends up being it, not a bad time to upgrade to a 2nd gen 12valve piston pump.
The IP could go with age. How many miles r on it?
