Hi everyone, I have a 2017 Cummins 68RFE with DRD tuning and a full clean bill of health if you know what I mean.
My truck has developed a problem in the last 2 weeks truck at WOT about 80-85mph the truck will just cut out its like it falls on its face rpm don't drop but they just stop at about 2200rpm and I was watching to see if it shifts but it stops in 5th gear.
I have found it doesn't do it if I accelerate slowly.
It will run right up to 100mph.
I have never had this happen before.
I don't get a check engine light or a DTC codes?
