Ford 6.0 Code P2284
I purchased my 2005 F250 6.0 4x4 new. At about 80,000 miles I performed all engine updates except head studs. This engine has always run great. Fast forward to 191,000 and it still was running great, towing my boat in town about 35 mph the engine just shut off. I looked if over for about 20 minutes and it started easy and ran great for another 15 minutes and shut off again. It logged code P2623, I had it towed back. The next day it started easy and ran great, I let run for 30 min with no problems. I Order and replaced the IPR and ICP with oem Ford parts. It started fast ran great for a minute then started missing and logged code P2284. looking at my scan gauge I can see its going into a default mode with the IPR at 33 and the ICP at 875. These numbers read correctly for the first minute. I've looked the harness over pretty good, but I haven't found anything concerning. Any ideas are welcome.
What is your ICP & IPR while cranking? You need to look at volts as the PCM will "infer" an ICP if the sensor is being wonky. Scan-gauge can read it, just takes a different entry:

There's a whole sticky in the 6.0 forum showing what the values should be. I believe it's around 0.80-volts which equates to the ~500psi needed to start the truck.
