It's just like the old 6.5 DB2 4911 pump. Hot no start. Let it cool and do nothing more and it starts. This progresses to a complete no start with the Dmax and in this case it is ball seat erosion from 2003 era second iteration injectors. A little sniff bumps the engine cranking speed up enough to move enough volume to get the pressure required to start.

To the best of my recollection the scan data will not show valid during cranking. Either way this is a textbook example of a condition I've seen many times before but not in recent years because most of those old injector bodies are long gone thankfully.
