02 4WD 140k miles

Trying to sell my Rav but still can't solve this problem:

A couple months ago I was sitting at a stop light, went to step on the accelerator, but then the engine shut off completely. No rough idle, no hesitation. Straight cut from power. While off, the dashboard lit up like a Christmas tree. Turned key off then on, and it started right away with out a problem and drove off like nothing happened. No codes thrown. A couple days later same problem; engine cut off at idle. To this day it never has cut off while in motion, only at idle. Battery connections are solid, but I haven't checked any ground wires. Where should I look? I called two shops and 1 of the guys kept it for a couple days and of course couldn't get it to replicate the problem. Both shops told me I most likely need new cats and sensors. When has bad cats and/or sensors made a car shut off??

Backstory:

Last October I took the Rav up a mild off road trail. Mainly fire service road with a few sketchy sections. I took a wrong line and the front end came down hard on a rock forcing the exhaust pipe upward, snapping a bracket and punching a hole in the bottom of the cat. I had a pretty loud exhaust leak for about 2 months and patched it a few times with JB weld, but didn't last as it was too hot for the weld to hold up. It was at this time where the engine randomly shut off. Then I took it to the shop to get the hole welded for the time being and that's when I was told I need new cats and sensors. Both cats were replaced about 25k miles ago. I can't imagine I need new cats again unless they are aftermarket??

Top left red circle: This 02 sensor is loose and broke free after that impact on the trail.
Middle red circle: This was the hole created by impact.
Bottom red circle: This is where the rock hit.

I highly doubt your trail incident, cats or O2s has anything to do with the shutting off problem. Totally unrelated IMO.

The fact that after the engine stopped the dash "lights up" makes me think the ignition effectively shut off and then came back on as when you first turn the key on. I'd suspect a defective ignition switch or related wiring.

Can't say for certain but here is the experience I've had: Faulty crankshaft position sensor: engine shuts off randomly in idle or drive, dashboard lights up. Engine starts back up but will die again after a while (same day/next) Faulty MAF sensor: irregular idle, stalling when idle (almost always) Hope this helps somebody.
