New injection pump?

It's a 93 7.3 non turbo. The other day on a cold engine it would stall if I let off the accelerator quickly. It fired right back up each time. It did it until it warmed up. I took it into town and it did fine until I got on the highway it started loosing power then it would get random boosts if I moved the accelerator around a bit. I got father into town and it got worse. It lost so much power it started jumping. Almost like a light death wobble. It didn't matter what terrain. All this time my fuel filter was coming on and off so while in town I got a filter. I headed home and I was almost home and it stalled. It fired up and I made it home.. Changed filter and still the same. About a year ago i put a return line kit on it. A month ago I put a lift pump.. My truck has 193k miles. I don't know what the problem is. I'm thinking new ip and injecters

if the pump and injectors have never been changed, you are way overdue.
i would eliminate the possibility of sucking air into the fuel system first though.

Mine did this recently too. Stalling and all. Was definitely the fuel, was bad enough i went through a few filters before it was all clean and running right again. Fuel treatment/atf is your friend here
