Intermittent Stalling chaos...6.2 gas motor

[BigWalt]

2017 Ford F250 4x4 with 6.2 gas motor. Only 5600 miles.
Intermittent stalling, MIL on then flashing rapidly....just prior to stalling transmission bangs into gear.
Other dealer replaced wiring harness, fuel pump and pin fitment at fuel pump connector....do not know if that was original complaints. Their Oasis / warranty repair history description is vague...

Anyway, truck came to us, No hard fault codes, couple memory codes from BCM and ABS module, they're U codes....I don't recall what codes but will write it down and post it here.

Perform Live Network test, all are in green, nothing turns red.
Data monitoring various PIDs, nothing stands out.

My next step is find out the common denominator of multiples U codes then go from there.....I suspect loose ground or bad pin fitment.

What bothers me is MIL flashing rapidly but no codes stored in PCM or any other modules.

Anybody has similar situation?

May be some clues in the mode 6 data.

No clue in mode 6. nothing out of ordinary.

only thing I found was very loose G112 connection on driver side inner fender.
remove n clean, then secured it good.
road test 10 miles, went over speed bumps, rough road and railroad track. cannot recreated stalling.
