Dead truck???
So I was driving to work and the truck lost throttle response. There was very little of it! Came to a stop then it didn't barely want to move, pulled over then it died on me! No clue what to look at! Please help. 2005 6.0 232k miles

Unplug it and then try to start the truck. That forces the PCM to use default values. If the sensors bad and there is enough pressure, it will run.
You can even remove the sensor and look into the hole and see if you can see oil inside...that may confirm a bad STC.. no oil, we'd know its toast.
The STC fitting connects the high pressure oil pump to the oil rail which feed the injectors... without pressure, your truck won't run. They fail unexpectedly, common for the 05-07 truck and mostly UN-diagnosable without a live data gauge.
You need a Scan Gauge 2 from Advance Auto (use code TRT30 to save $50, buy on-lin and do in-store pick up), they cost $159 and then it needs programmed (You Tube) for X-gauges to read live data or Torque Pro ($5) from the Android store and an ELM327 OBDII blue tooth device (Ebay $20) to really figure out whats wrong or we could just start guessing... but we don't want to really do that, its expensive.
Have a BUDDY with a 6.0 that has a gauge or a member near you in Great Falls Montana? that can help? Can borrow a code reader from Advance Auto or Auto Zone to read some ODB codes maybe?

Are you thinking also Dummy Plug and Stand Pipe o-rings Mike? In your experience, how slow of a failure is that, versus the STC that Randy mentioned, which is a pretty rapid failure of HPO pressure... Both strong possibilities...
Camo: do you have any history (records) you can check to see what has been done on the truck in the past?

Scott From what our Ford techs have mentioned before
STC failure shows 0-150psi ICP
Dplug or Standpipe usually hits in the 150-300psi range
of coarse every case may be its own unique thing but

DP's were hard but not shot, however the STC I pulled apart very easily with my fingers once I got it out.
Got's to have something to see things live. There ought to be a big sticker on every 6.0 that reads "Get something to check vitals"
I drove an 04 to the silage pile a few days ago with the CEL on, drove me nuts wondering what the issue was, but it's not my truck.

Let's see what live data says before spending any money on parts.
Need ICP, IPR, ICPV, FICM power, FICM sync and those numbers should be from KOEO and cold cranking. We also need main voltage and rpm while cranking.
