I've had this truck for years now and finally get around to driving it full time and I've run into alot of problems. When I bought this truck it ran fine and I would drive it on the wweekends. The truck now idles fine and runs in first gear but when I shift it into 2nd it will run a little longer the sputter and bog down, but if I push in on the clutch it will go back to idling fine. I replace the fuel pump, cleaned the tank, replaced inline pump, pip sensor is good and timing has been checked. Anyone have any ideas of what to to next?

Vacuum leak ?

I'm pretty sure I've checked, but will look again

Sounds like it can't handle the load. I would check fuel pressure and make sure your ignition system is in good shape, plugs, wires etc. You didn't mention fuel filter but I would do that first if you didn't recently replace it. Finally,make sure the converter is not blocked. You can verify with a vacuum gauge.
