1987 Chrysler Le Baron fuel problem

We recently replaced fuel pump. Filter, and fuel pump relay for the car it ran fine for 2 wks then when I was on the highway it started to slowed act like it wasn't getting enough gas and it would p/u and it did that for about 4-5 times than it was ok. I put fuel injector cleaner and dry gas inwhen I filled the car up, it was still doing the same thing so the next time I filled up I put more fuel inj cleaner in the car, than it started running really bad, it was acting like it wasn't getting any gas almost buck kind but not really it seem to not be getting enough gas than I was out and the car started running really really bad I pulled into a parking lot as I was pulling in the car died. I sprayed carb cleaner in the carb area, the car started ran about 10ft then died again I could get the car to run but it would die every 20ft or so. Please help going crazy trying to fix it please help thank you so much lisa
