If you have not already, I would change all fuel filters. E-10 kills these engines.

all filters have been change
If its maintaining 702 psi all the time, I have to assume its getting enough fuel to the HPDI pump, now whether thats reaching the injectors, or if the injectors are spraying enough fuel, thats another story.
Do you know how to do a injector leak down test with YDS? Might help you pinpoint if the injectors are spraying close to the same volume.
Is the WOT rpms still the same as its been?
What does the O2 sensor and draw tube look like?
Spark plug condition?

how do i do a injector leak down test?
the o2 sensor and tube are clean
plugs are new
i dont know if top end is the same as i did not trust it to take it out yet
Are you really familiar with YDS?
Do you see the test area in the program for doing injector tests?
Do you know where to check HPDI fuel pressure readings? You will need to be able to toggle between the injector test section, and those HPDI readings.
And be able to start and stop the engine at least 6 times (6 injectors).

I've had the same problem after running a few hours. Pumping the fuel line bulb at the engine got past the stalls.
