Are you getting a check engine light? Go to autozone or whatever you have nearby and see if they can pull the codes. If it's a sensor it should be setting a code that will tell you which one is bad.

On alot of the discussion boards and forums, I am seeing people mentioning that when the CPS goes out the truck will throw codes for other issues and not the CPS itself, other times it will not allow the reader to connect with the truck at all and only after you disconnect the CPS will it allow the connection. The biggest problem is I do not believe I can make it to my nearest part store for them to attempt it :taz
My truck did the exact same thing. However it was the TPS (throttle positioning sensor). Left me on side of Hwy 51 for about an hour in 24* weather, 4 hours from home. Would not crank till after I spent an hour on phone with AAA explaining where in the hell I was. Then cranked and I drove to Tampa to get it checked out
Apparently the ECM in these can go bad and its a common thing, ex-girl of mine was having the same issue in hers
Now you have given me something else to worry about, after doing some searching around this can cause the same problems I am currently experiencing.
Went out last night to mess around with it. The problem is getting worse. It will not run for more than 2 or 3 minutes before it dies now, it will restart for another minute then die, on the 3rd attempt all it will do is crank the engine, it will not turn over.
I had the same issue on a Land Rover Discovery I owned. I chased it for about a month until I finally figured out the problem after it left me sitting on the side of the road. Mine would cut out when I was sitting in traffic or after I had stopped for gas, it wouldn't restart until the thing had cooled off. It was the CPS you're talking about. Mine was relatively easy to access I guess. It was tucked up inside a pocket between the transmission and the engine that was just small enough for me to not get my hand into. I had to use a 6" long allen wrench to get to it. Putting it back in was a pain in the rear though. But when I replaced it, everything was fine.
It's been my experience with fuel pumps that they are either working or not working. I've replaced/rebuilt one in the Land Rover and replaced 3 in the Astro vans I've owned. Everytime, the engine would just die and not restart until they were replaced. I had to replace one in my wifes van in the parking lot of our church! Kind of wierd dropping a gas tank in the middle of a church parking lot... ha.
Anyhow, hope you can get this figured out. Nothing worse than chasing electrical issues. :toast
start with the cheapest and or easiest fix out of the suggestions.
