It could be electric fuel pump stall. The pump isn't pumping fuel fast enough. This model may have a inline fuel filter before the fuel pump as well that might need replacing.

My friend had the same type of symptoms, there is a spider wed style od hoses under the intake that delivers fuel to all the cylinders that he found to have hairline cracks in it. Found out this is a know problem especially in the 4.3L Vortex

I think you'll find sender & pump are all one assy. What is the reason for changing. If it's the gauge, have you removed, cleaned contacts & re-attached wire plug at pump/sender assy, to see if it would cure your problem? Personally, it's not something I'd want to do twice in a short time, so if I was replacing one (if parts are available to do so) I'd replace the other, unless difference in price was extreme.

probaly a fuel pump its common for vehicles to do that the best thing to do next is a fuel pressure check to verifiy its the pump
