: Defueling at 2-3 shift

This started I guess a couple weeks ago. I don't often accellerate from a stop with the pedal to the floor, but I did it a couple weeks ago and again yesterday and my truck shifts fine in the 1-2, but when it gets to max rpm's and is about to shift to 3rd, the rpms stay around 3000 for a second, then it feels like it defuels and loses power. If I lift on the throttle it shifts fine. I have my predator set on 65 and haven't had this problem before. No codes.

When my truck did this, I changed out the fuel filter and it fixed it.

That's what I was thinking. It has been about 20k since I changed it and figured it is time to do it
