Update: This site is so awesome !! I am so Thankful for all response's, idea's and suggestions !!!
I believe I have resolved my "Unexplainable Stuff Off" with the help of Clay and noting his thought's of the following:
""Mark, when you get a chance give me a call sometime today and lets see if we can sort through all of the diag info you are being fed. Like the guys said, alot of it seems sketchy. Could just be something simple we need to find, and not necessarily throw money at. ""

He worked with this "NON-MECHANIC" and helper thought-out this entire ordeal.
Clay shipped over-nighted my part and saved me around $140.00 -Just on the part !!
Then Clay sent me emails with "How To " - Whereby even this "NON-MECHANIC" - though over the phone 50 million times- Install and replace ..
Again GUESS WHAT - It worked and truck fired right up !!! Incredible !!!
Let truck idle and ran truck at 1800 rpm for 1/2 hour - truck temp is up and no shut off..
Will keep everone posted and like Clay said" It just kills Clay to hear that Dealerships and Shops always seem to go for HPOP or Injectors.. Clay says try all other things before the big money..
THANK YOU , THANK YOU CLAY !!!! Your the BOMB !!!!!
