Default Engine issue?

I originally posted a thread on the drivetrain section thinking maybe I had a transmission issue . But, now I am not sure thats it. I think more an engine issue.
In the morning I crank the truck and it starts fine. Drive down the road about a mile and the truck starts to lose power. I have foot on the gas and it slows down . It shakes and shutters a bit and if I release the gas it recovers and resumes normal operation ,until I start again and a repeat of the same thing. The engine has stalled on 1 or 2 ocassions while driving . BUt it restarts immediately. It just wont move forward when it starts is shaking and shuddering. Then as quickly as it began it recovers and doesnt happen again. It only happens when first started. Doesnt matter what time of day that happens. Truck stalled twice this morning. I only drove the thing about 3 miles. So, I amm open to any possibilities . Throttle body,fuel injectors, ???. The truck has 52000 miles . New plugs,wires,coil,air cleaner. NOthing internal has been changed. I have an 86 xlt 2.9 engine automatic.
When engine idles it idles fine never indicates its about to throw up on me. This is my first Ranger and I am not that familiar with their quirks. I know about carburetor engines not injected.
HELP!!!! Thanks

Default Re: Engine issue?

This morning I was going to clean my mass airflow sensor and see if that helped. Dont have one that I recognized in area of where it was supposed to be. So,I started looking around the throttle body and saw this thing attached to it with 3 wires going to it . One wire was green ,one was orange, the other was black. From its location on the throttle body I deduced that it was the throtle position sensor. Further nspection I found the green wire cut. This wire according to my 86 wiring diagram goes staright to the electronic control assembly . The other 2 wires work their way finally getting to the assembly after connections with various other wires. Since the green wire is a direct wire to the assembly I think its the power to the sensor. If it is cut the sensor wont allow the throttle to operate properly thus causing hesitation,bogging down and eventually stalls. Because the throttle wont move. Am I correct? Or am I fishing in a barrel?

I'm thinking you found your problem. Hopefully there is enough wire to splice them back together.

If not, you may beed to go to the junk yard and see if you can get another plug to splce in. Barrel splces with heat shrink tubing over them is the best way to do it.
