2018 f150 diesel dead spot/ engine cut

I have a 2018 f150 diesel just turned 5000 km and everything I drive the truck after it has been sitting it misses/ cuts the engine in the 2-3 shift .. acts like engine cuts.. anyone else experience this ? It was fine until about weekend ago ..
It's not a wide open shift it's just a normal 1/4 throttle when it happens..

Mine does that occasionally. It's very odd but doesn't happen very often so I haven't bothered taking it to the dealer. Just after sitting, right? Not after it's warmed up?

Mine never does a 2-3 shift, it always goes 1-3 unless i'm in tow-haul mode. Sometimes I get this on the 3-4 shift on the first shift of the day, and then it's ok from there. I had a 17 F350 that did this as well. I think it happens when the trans is cold, probably a software glitch.

I hope ford comes out with a better shift strategy for these soon.

Mine did that as you described after sitting or the first shift of the day. However, I havent noticed it since the egr recall was done.

Because with EGR recall there was also a new PCM and TCM flash. Like I said, take it in and complain, there are even newer calibration that would be much smoother and better power!
