Losing power- Dodge Ram 2500-diesel
Hi, I am new member, my name is Karel. My Dodge 2001 is losing power from time to time. I got new fuel pump (in tank), the Dodge dealer did not find anything wrong; . It starts always good, but mostly at times when I do not need power (going down the hill or just brushing the fuel pedal for a whille) and after that when I start to push the fuel pedal, there is no power, it feels like it is going only on two cylinders. I have to stop, exersize the pedal for few seconds then it starts to catch a breath and it goes again.
Anybody have some idea what it could be ?
