Hi
I would hook up a small tank of diesel as close to the lift pump as i could.Add a fuel pressure gauge and try it again.You could have a line were the inside is collapsing and plugging the fuel flow,either before the lift pump or after.
A fuel treasure gauge will help you see if the lift pump is making pressure when the truck stalls.
I have had a rubber line falling apart inside and the bits of rubber would pile up and form a plug either in a fitting or elbow and act just like what you are describing.Wasted a lot of time and filters finding that one.
