Have had this problem happen intermittently and have gotten zero help nor seen anything similar before.
Have had the same 3 codes for the last year or so (MAF sensor, O2 sensors, catalyst heaters.)

The car will start fine in the morning, drive to work, no issues whatsoever. Starts fine leaving for lunch then starts fine on my way out after work. It’s inconsistent so hard to replicate but at this point, after driving for the 3rd or 4th time In the day I’ll go out to start the car, it’ll crank, turn over, rise up to around 1.2k rpm, then in one smooth motion drop back down and die.

No new codes, no abnormal data, have tried disconnecting the battery for a bit, clearing codes, pedal down, in gear… I’m completely out of ideas, I’ve got an Ethos scan tool, not sure if there’s a way to reset the ecm or do anything else.

There is literally not a single thing out of place that would implicate this problem and I’m about to just scrap the car
