Check / clean all electrical connections. Replace fuel filter. Check / replace the fuel pump & EEC relays - they're known to have intermittent problems. If that doesn't solve the problem, check the fuel pump(s). I believe your setup is basically the same as my van - a low-pressure " lift" pump inside the gas tank & a high-pressure main pump on a frame rail. Normally the pumps either work or they don't, but a bad connection could cause an intermittent problem.
