2022 Freightliner Cascadia engine stalls intermittently

The repair was completed at my trucking company's terminal last night. Unfortunately, the mechanic who repaired my truck did not tell me what was causing my truck's engine to stall. The mechanic did not show me his notes either. I would have liked to see the notes as well though. I was on a hot load that had a delivery deadline at midnight. So I had to immediately hook up to my loaded trailer and drive to the receiver once the repair was completed.

I agree that heat soaking seemed to affect this as my truck's engine never stalled when it was cold.

I am glad that the inferences I made about what the fuel and water temperature gauges did when the truck's engine stalled are correct in what they would indicate about the causes of this problem. Some of the things I didn't know about trucking after many years of experience made me feel stupid. Several people here accused me of trolling for not knowing these things after having many years of experience. Part of the reason I created this thread was out of vanity to make myself feel intelligent if I were on the right track. Part of the reason I created this thread was out of curiosity. And the third reason I created this thread was for the practical purposes of knowing how to diagnose this problem if it happens again.

If the truck's engine ever starts stalling intermittently when I first turn on the truck's engine, and if the truck's engine does not stall while the mechanics are working on it, I can tell the mechanic what the truck's gauges did when the truck did stall to help the mechanic diagnose the cause of the truck's stalling.

 

Usually neither. I do something in between those two extremes.

Usually when I turn the key to on, I do pause for about three seconds to let the computer wake up and go through most of its internal cycle, but I think I usually start the engine before the internal cycle is 100% complete.

 

Update: My truck's engine stalled again last night. I looked at the gauges immediately after the truck's engine stalled, and the fuel gauge and water temperature gauge and my air pressure gauge all still worked. So it looks like this is probably not an electrical problem.

When the truck's engine stalled last , the engine was hot. So it does appear that heat soaking is an issue. My truck's engine has never stalled when it was cold.

Do you need the last 6 of the VIN of the truck or the last 6 digits of the VIN of the truck's engine?
