1996 Dodge Van Dodge Ram Van Fuel Problem

I have a 96 Dodge Ram Van with a 5.2 liter V8. When it get to about ¼ tank of fuel, it starts to miss and a most speeds above a crawl it stalls. It will restart and usually I can get it to run enough to get it to a gas station. About 4 yrs ago the problem started at ¼ tank and progressed to ½ tank. I had the fuel pump replaced and it only lasted about a year and it started again. That pump was replaced and about a year ago it started again. For the past year I have just not let it go below ¼ tank. But the other day it stopped at ¾ tank and I couldn’t get it to run enough to get it to a gas station.

Is there a problem with this vehicle and/or engine? Any ideas what I can try?
