2022 Freightliner Cascadia engine stalls intermittently

How did you learn what a can bus problem is on a semi-truck from paying attention?

 

I searched for "can bus" at this message board, and the only reference I can find to "can bus" here is when Ridgeline wrote "can bus" on this thread. So Ridgeline didn't learn of can bus here at thetruckersreport.com. I wonder where Ridgeline was paying attention to learn of can bus.

 

Update: I had the truck's engine turned off for eleven hours last night. When I first turned on the truck's engine this morning after the truck's engine had been off for the last eleven hours, the truck's engine stalled on me. This is the first time that the truck's engine stalled on me when the engine was cold. So this problem is not strictly about heat soaking.
