Excursion 7.3 Low Power under Load HPOP?

My excursion 7.3 began losing power under load, having had starts, and either stalling or starting very slow at stoplights.

I have replaced the ICP, IPR, and also dropped and cleaned out the gas tank and screen filters.

I created these 2 short videos
showing the HPOP pressure and duty cycle. Wondering if my next step is to replace the HPOP? sorry for the quiet audio they were made with an iphone videotaping the cargauge pro readouts.

Any help is appreciated.

Are the replacement icp and ipr oem parts?

Assuming the oil level in the truck is good?

Might be a high press oil leak. How many miles on injectors? Can you do a Cody test?

HPOP is rarely the problem. The ICP shown is static beyond reasonable expectation. Paul's questions above... plus does the fuel filter look black?
