check basics first - dist cap,rotor,plugs,etc.Then put a pressure gauge on fuel line and check reading to specs for truck. you may need a fuel pump

Three speed automatic? If so the TCC solenoid is bad.in the transmission. Its under the side cover on the driver side. You can unplug wire connector going to front of transmission so you can drive it until you get it fixed. It will use more gas due to no torque converter lock up.

SOURCE: running rough and wants to die
Have the fuel pressure at the fuel rail checked. If you just want to throw parts at it: Fuel filter by the tank first. Fuel pressure regulator next. Order of ascending expense and likely hood. Does the fuel pump hum louder lately? The fuel pump may be on it's way out. It's not getting enough fuel to do anything but idle. Why that is takes some investigation. Somebody like Auto Zone may check your fuel pressure. If the fuel pressure is good, bad spark plug wires are the next guess. Lift the hood and run the engine in the dark (take the light bulb under the hood out if it still works to do this) If you see little lightening bolts traveling over the engine you need new plug wires. If the fuel pressure is good, the wires are good, change the spark plugs. Good Luck!
