The heat shield was loose and looked like it was turned. I pulled the heat shield off. I'll see if that works thanks. Silveradosid

Hello So I'm stumped on an issue. Driving down the highway on my way to work the gauges died and the truck died as well then turned back on. The cel came on and upon checking it there were alot of loss communication codes (tcm,pcm,bcm,abs,ect). I check all of the modual connections, lifted up the fuse box and check the plugs under it. I looked over all the chassis wiring and grounds. Aswell as the battery connections and grounds. I also checked all the plugs and wiring under the dash and everything is tight and nothing is corroded. Of course while checking things on my scanner I accidentally cleared the codes but I did right a few down. I'm just really perplexed. Could it be a can issue? If so where could I start? It only did it the one time but if it did it once I'm sure itll happen again. Any help would be appreciated thank you.
