I have 06 ram 3500 5.9L diesel which died while driving down highway and now will start but only idle 1/2 minute. When first started the fuel pump in tank thumps five time and then engine runs about 1/2 minute and then dies. I replaced fuel pump in tank and filter but still does the same thing. I replaced injectors two years ago and now since with new fuel problem oil is growing again. Anybody had this problem before and figured out how to repair this?

 

If your oil is getting diluted with fuel, I'd start by pulling the injectors and getting them tested.
