Appreciate all the great feedback. To answer some of the questions...

-Yes, I installed the last new cps as a preventative measure, not as a fix. I kpet the old one (still working) in the truck as a backup.
-I have installed a UVCH before on a 94 7.3L so I am somewhat famaliar with the set-up. I have a test meter, so I'll be sure to perform the Ohms check and report back.
-In regards to the Edge... Yes I know. I bought it when I first got the truck. I like the digital guages, but am not happy with the generic tunes. Will be making the shift with DP Tuner shortly. I have already have the Screen go blank and the Engine ECM wiped out once because of the Edge.

Note: I have performed almost all of the preventative mx tips mentioned on guzzle's site. I don't like being one of those people who is stranded.

Thanks again for all the tips! Will start troubleshooting when I get back from work tonight.
