Needs some ideas. I have a 2000 4wd dakota 4.7. Recently within the last 2 weeks the engine will start fine and then ideal for a few seconds, then the rpm's drop out and it spits and sputters and then dies. Once I restart it, it runs fine. If the engine is warm, I have no problems starting it. The PCV is three months old (just took it off again and cleaned it, as it had some of the filmy residue discussed in previous threads), the plugs I just replaced thinking that would help the problem, but it does not. I am hoping this is not a fuel pump problem. Any ideas would help...
