Fuel problem?
The problem only happens on start up until it’s warm or b/w 60-80 mph. I’ll be on the highway and it feels like it’s running out of fuel my foot stays steady on the gas pedal and slowly decreases in speed for about 30-45 seconds then feels like it coughs a clog up and then runs fine. Does this when I let off throttle and then go to accelerate again. Or on start up I’ll let her warm up try and give it some gas to see if it’s acting up again and I’ll be flooring it and will barely rise on my tach and white smoke comes out the exhaust... ideas?

New fuel and air filter are always a good cheap place to start. I believe there is a schrader valve on the drivers hand side of the fuel bowl, rent a fuel pressure test gauge while you're at the parts store if you don't already have one. Is it possibly the 1/4 tank issue people talk about? Where your pickup boot falls off in your tank.

Mine starved at 1/2 tank this weekend I’m gonna take it off and do the hutch mod I ran injector cleaner and it runs a lot better but still either feels like it’s clogged or starving only on the highway. Approx. 65-70 mph and when I try to give it gas to stop the clog it backfires with black smoke?

Found the problem. Crack in the oil pan. Checked the oil it was low so I put some in had an 8 hour drive ahead of me ever since I put oil in it ran better, on the drive truck ran dry gauges all read fine and had oil before I left. Oil holds back pressure for it to start to feed the injectors fuel which thinking about it now it was the cause to any problem I had with the truck. Live and learn I guess. Hope this helps anyone that has a similar problem
