I forgot to add, look into a bad hub, brake dust, or leave it alone until it is a all the time problem.
If they are turning off after you start driving I think it is going to be really hard to find the culprit and you are going to waste time and money looking for a grey ghost.

 

Thanks for all the responses.
The Amigos appear about 1/2 the time I take the truck for a drive. Of that 1/2 time that they appear about 80% of that time is right after I release my e-brake/parking brake/emergency brake/hand brake to drive off. Its instant. As if its my e-brake that is causing it(wire short near the e-brake handle maybe?). The other 20% of the time they appear is less than 1-2 minutes after taking off after releasing my e-brake. In other words, NOT right after I release my e-brake but within the minute or 2.

 

...so then I finally found a suitable incline in this flat swamp land I live in to do an HDC test. Well, on the very first run I use the 4x4 shifter to drop the transfer case into "L"(not the diff lock L) and the tranny into "1". On the first HDC descent the 3 Amigos appeared right away and my HDC failed and I had to put my foot on the brake. I then drove it around the block and came back to the same gravel levee descent as before and the same gear configuration and guess what? No Amigos! I did the same descent in tranny gear "2" and "3" as well and no Amigos. I then wheeled it to the nearest gravel alleyway and tested my ABS and my TC and both worked flawlessly with no Amigos to be found. I wonder if I just had some gunked clogged in one of the lines in my brake module and that first HDC run broke it loose. Hopefully it will stay that way. If not, its off the the dealer.

BTW turns out my cruise control situation was remedied by physically pushing the vacuum bladder back and forth with my fingers and man handling the lines. It must have been stuck.

 

Neither the Hill Gecent or T/C will work although the ABS may depending on the cause of the 3 Amigos.
Find a mechanic with the proper scanner, make your lights come on and get the codes read, other wise you will never figure out what is going on.
