2018 CRV multiple codes mystery!

[Dr Dirt]

2018 CRV with a 1.5. Engine stalled while my daughter was driving. The battery voltage was only 11.5 volts so I installed new battery and the engine fired right up. Every DTC light was lit and I measured the voltage at 14.6. I cleaned the battery terminals and measured to ground on the chassis and had 14.5 volts. I drove the car a few miles and the codes cleared. A few hours later my daughter said that the codes were lit again and the engine stalled so I towed the car home. The codes are not regestering on two different code readers! Even my Autel reader cannot clear the codes and I did reboot both electronically via radio volume knob and disconnecting the battery terminal. Anyone ever experienced this ?

Curious as to what codes. Would have to start there first. Battery would not cause a stalling issue, it's a capacitor, with engine running, unless it was severely internally shorted would not show 11.5 volts. Rhyme and reason for everything.
