Hi all. Right now my 93 d150 is running fine sitting in the yard, and if i got it on the road it would likely cut out intermittently, or could get to the point to where it will hardly pull itself, or might even stall out completely and not start and then later start with some effort and run fine until it doesn't. I'm at a loss. I hope someone can impart some wisdom here. I'm stumped!

 

Sounds like a fuel delivery problem.

 

Disconnect the MAP censor and see if it runs better, if it does replace the sensor…
