RE: 21 degrees start then shut down
according to the fault code lookup on quickserve:

Code:
1. &nbsp&nbsp 771 &nbsp&nbsp&nbsp Brake Switch Circuit - Voltage Below Normal or Shorted to Low Source
2. &nbsp&nbsp 3697 &nbsp&nbsp Engine Control Module Calibration Memory - Bad Intelligent Device or Component
3. &nbsp&nbsp 3698 &nbsp&nbsp Aftertreatment NOx Adsorbing Catalyst Warmup Error - Condition Exists

I have a cm2250 and according to quickserve codes 771 and 3698 don't exist for my engine.

Either way it looks like 3697 is what caused the stop engine light and engine shutdown.
How were your batteries when you tried to crank the engine this morning?
Possibly a low voltage situation when you first started the truck.
