Sounds like your in the very early stages of fuel starvation from a highly restrictive fuel filter or the fuel pump is losing the needed fuel pressure.
If and when you change the fuel pump, get the fuel pump and sender assembly as a unit. DO NOT buy an aftermarket fuel pump. They have very poor reliability and cheap quality controls.
Only buy an AC-Delco fuel pump assembly and when that change occurs, change the fuel filter.
Another area is clean the black ground wire leading off the fuel pump assembly to the frame and clean that also. Apply grease over that connection when reattached.
