An update. I now carry an OBD scantool with me and check it every other day, so far no codes are stored that I can see with my tool, and the problem has not happened again. Even took it offroading this weekend without incident.
I posted this in another forum:
"Several members suggested Alldata, so I got a subscription, and pulled more information on the codes. AD also shows the wiring diagrams, in case anyone needs them. I am having to learn this as I go, but it looks like the Controller Area Network (CAN) went down. I kinda, sorta, think all these things have the Totally Integrated Power Module (TIPM) in common. Is that it? I dunno, but from suggestions here, I made sure all fuses and relays are seated.
Maybe this information can help others. I'll keep reading, and then read some more. So far the truck drives fine after having connectors and wiring checked and making sure all items are seated and without corrosion in the TIPM.
Just checked the topside of the TIPM, and all the fuses and relays, and a couple of the relays and the larger fuses might have been elevated by a millimeter or so, so pushed them back down straight. The post connections on the side of TIPM were all very tight, but took them apart and checked for corrosion, but they were all shiny and got tightened down again. Checked the main ground and it was shiny and tight."
