CPS failure under high heat??
In my 2002 F550 7.3L Powerstroke, the engine quits with symptoms just like what others describe in postings on this site. It acts like a cam position sensor failure. The truck only has 16,000 miles on it. I use it to tow a heavy 5th wheel and the part seems to fail when its hot in the engine compartment. The engine and tranny are NOT overheating - it just quits suddenly, the tach drops to 0, sometimes it restarts itself because the truck is still rolling. Other times I have to pull over, raise the hood and wait for it to cool down. The Ford dealer where I bought the truck says it's not throwing a code so they don't want to fix it. Any ideas on a fix other than continuing to replace the part? Anyone else having this experience??

This is classic symptoms of a failing Hall effect sender - just what your CMP sensor is. If the dealer will not fix it, it may be worth your time and effort to just go to International and get a CAMP sensor for your 02 T444E. That's thier version of the Powerstroke. It's exactly the same part except for the price. About $60.00 less. It's a very quick and easy replacement. It takes about 5 minutes if you know where to go and how to do it. It's mounted on the front of the block at about 10:00 in relation to the crankshaft pulley. One plug, one bolt, some gentle but firm turning and pulling and it's out.
I also have a 550, there is just NOTHING that I would be afraid to tow. LOVE it.

Make sure you have a nice crisp strong socket and you are on it squarely. If you round it off, it ends up taking a lot more than 5 minutes!
