Have you recently done any repair work to the fuel system ? Do you see any fuel leaking from top of injectors ? How full are the fuel tanks ? When is the last time yo changed the fuel filter ?

Could be a weak fuel pump............
Take the Schrader valve core out and hook a hose and pressure guage to the outlet.........crank engine see what you get for pressure, should have 4-6 psi from a good lift pump.
Volume test same place hook a hose to it crank over the engine 10 seconds you should get 1/3 pint of fuel minimum or 1 pint at 675 rpm in 30 seconds... engine running
Important the fuel shutoff solenoid (FSS) wire on the IP should be disconnected if you do not want a start just cranking. Re connect FSS after test complete.

Contaminated fuel or a bad ip can cause this problem . Mine was doing this untill I changed my ip . I have read on here where you can take the top off of your ip and clean it out to fix the problem . Maybe someone with more ip knowledge will help you with this one .
