I drive a chevy silverado duramax
Ill be driving normal speed in the city or the freeway when for some reason I loose power
Where my rpm cannot go over 2 ,I'm usually stuck on the freeway at 60 to 65.
Now if I stop and turn the truck off then ill be good for a while (5 m to an hour sometimes).
I also have a chip connected to my truck ,at first I thoght that was the problem so I set it at 0 (which it means is desconnected)but the problem still there.
The problem started like 6 to 8 months ago ,it use to happen once in a while but now is happening every day all the time.

I really apreciate any help
Thanks

Have you tried changing the fuel filters? If the filter is starting to plug you will loose power and after you shut it off and turn the key back on the there is extra fuel from the fuel pump setting there so it will run better until that extra fuel is used up and then you will start to loose power again.

Thanks, I will give this a try.
