1993 GMC Other • V8 2WD Automatic • 211,000 miles

I bought a 1993 Topkick from Uhaul a little over a month ago and I have a problem I need to troubleshoot. The truck starts fine and runs good for 5 to 30 miles and then the acceleration goes to nothing and the truck literally starts to coast, I pull over to the side of the road shut the engine off, restart it and it works fine for another 5 to 30 miles? I have changed the fuel filter which was dirty, but that didn’t solve the problem. Any ideas? Help would be appreciated.
