Like any oil leak - it can start to leak suddenly or it can be a slowly progressive thing.
An air test of the high pressure oil system is the proper response to a hot no-start. Since you have done the standpipes and dummy plugs, the STC fitting is the next most likely issue ... but do the air test.

IMO the best way is to buy the fitting that installs in place of the IPR valve. That takes a bad IPR valve out of the equation and it gives you an opportunity to inspect the IPR valve before doing any more work.
All that stuff can be found in the Tech Folder thread on troubleshooting a no-start condition.
DieselTechRon has great videos on air testing and hot no-start troubleshooting. Links to those videos are in the thread.

The reason I asked is that I had a "stalling and hard start when hot" that turned out to be a plugged oil cooler. The oil was getting so hot it had lost its viscosity and the pump couldn't build or maintain pressure. It would help to know how hot it is at the point the truck doesn't start, as in an actual temp reading, not what the factory gauge shows.
