I'm really confused! My truck cuts out goin down the road. It doesn't die though. It just loses power I give it more fuel and does nothin. But then put it in neutral and rev it up and put it back in drive. And it takes off. Changed fuel filter and put a different lift pump on. Any ideas on what it could be is greatly appreciated!

 

Got a fuel pressure gauge? If not that would be my next step.You need to varify your pressure when it cuts out. V.P possibly. Nate

 

If it is pump. What should I put on it? Stock or something bigger?

 

Read some of the discussions regarding fuel & fuel systems then decide. You need fuel. Pressure & system is open for debate.

 

Sounds like a tps/apps issue.
