Engine/Transmission (1998.5 - 2002) Cutting out

[Duckslayer]

I have a problem with the ol'truck. The thing is cutting out on me really bad and it is not just when she is cold. It will do it when i'm going down the road even when running temp. is up and good. At idle she has cut out so bad that it has killed it before. I just took my comp box out to see if that was it but it is still doing the samething. When I had my B1 put in they check me pressure and it was good never droped below 10psi. So if anyone has or had this problem please help.

What's your fuel pressure at when it's cutting out? Even though you don't have gauges in your sig, I hope you have them in your truck.

you could still have a loose wire. Might have got a bad batch of fuel. . Change fuel filter. Definately check your fuel pressure. That equals lift pump possibly going out.

If your lift pump has low pressure or not working very possible that your vp44 is going out. Is it throwing any codes????
