00 Dodge Ram van 3.9

Have a problem with the above vehicle.It has an intermittant rough running problem.Sounds like it is starving for fuel and when it starts to happen there is a loud vacuum sound.Won't quite stall but also will not take the
gas.It did trigger a check engine light.Scanned it and scan tool indidcated that both 02 sensors were out of range and the upstream was shorted.Replaced both sensors but did'nt soilve problem.Fuel pressure runs steady between 45-50 psi however when engine begins to run rough gauge needle vibrates rapidly between 40 and 50 psi.Any thoughts would be appreciated.
