The most obvious place I would start is the fuel pump. It would seem that it's not producing the correct volume of fuel to the bowl. After that I would look at fuel lines, before and after the pump. The short fuel lines from the pump to the bowl are notorious for failure over long periods of time.

Just an FYI, I had a similar problem, and after replacing the fuel pump and having no luck, I traced every bit of the lines and found two pin-hole sized leaks on the suction side; the fuel bowl was emptying because it was sucking air. Think when you were little and had a soda straw with a hole in it....

Anyway, I couldn't find it at first. What I finally ended up having to do was unhook both fuel lines--suction and return, and plug one end, then hook up the outlet of a vacuum pump set to about 10 psi (use good hose clamps here--trust me!) I found two wet spots on the suction side that were just big enough to cause the problems.
