Case of the sputters?

Yesterday was a cold day. I didn't drive all day. About 6pm i took it to the store. While she was cold it cut out sputtered, i let off the gas, she caught her breath and off we went.
Today when she was warm it happened 3 times. Wasn't under a load, just crusing highway speed (65)

Any thoughts? Fuel filter is about 6k miles old. Clean fpr screen. I did just do the fpr bbq shim mod a few days ago? Is there any neg effects to that? Is it possible with higher pressure its "flooding "

Diesels in a sense can not flood unless you have a bad injector. Did you check the fuel pressure before and after doing the BB mod. You don't want more than about 70 psi at idle. How cold is cold? Are you running any fuel system additive like Diesel Kleen with anti gel?

Have you drained the fuel bowl making sure there is no water in the fuel? I would do a fuel pressure check.

I also gave you the sheet on how to check your HPOP line pressure with a DVOM. To me if it is happening after the truck warms up then there is either:

-Gelling in the tank making it hard to draw fuel from it
-EBPV is closing for some reason (like intake air temps below 37*)
-low HPOP line pressure.

Now by "unplugged the EVPV" you mean that you also wired the the mechanical part of the valve open so that there is no way for the valve to close by exhaust pressure?

The spring in the actuator should hold the valve open buts that's not saying that the oil solenoid isn't leaking past causing the valve to close
