N14 with 13 speed. Seems to hit neutral at various speeds until you let off throttle.

Sounds like clutch to me.

 

If it happens more often when you step on the throttle at higher gears yeah it’s the clutch slipping.

 

You have double under on that thing?

 

How much clutch free play do you have? Doesnt sound like you probably know what that means. But no offense at all ok. This would be the freeplay movement when you touch the pedal with your foot. IT should go down about 1-2"s with ease till it hits that hard point where you have to use force to push down all the way. IF there is none, chances are your clutch needs to be adjusted and you better do this ASAP!!!!!!. Takes 5 minutes to do it. IF you cant get any adjustment at all to give you that freeplay, then i would say you better get that truck in now for a new clutch.
If you are lucky enough, than its just that you have no freeplay. If thats the case and you keep driving like you are, you will toast the clutch and you will need a new one

 

I’ll second the clutch job.

Good excuse to go through the box while it’s dropped, rear main seal - motor mounts -

Aww heck, just dump $50k on some mods and chrome while you’re at it and ride in style a while.

Just don’t ask for my credit card details.

 

Does this just happen in high split?

 

Ive been seeing alot of times where guys just make an account and ask a question and then never come back to respond. makes people scratch top of head
