Thinking I’ll get it to a specialist of course, just hoping I might be able to gain some insight here if anyone else has been through it. The dealer tried pretty diligently a few times since I bought it in mid-2022, but can’t replicate it and hasn’t been able to diagnose it yet.

Other thought is to just drive it until it completely dies or won’t come out of engine malfunction I guess.
I don't think that's the best option.

It'd be nice if you got some good readings of typical things during the issue. Like O2 readings/voltages...fuel trims LT/ST...fuel pressure...
I bet there's a common issue here that just needs to be found. Some common ideas are the idle air control valve, fuel vent (maybe), SAI valves....

This is challenging to diag over the internet without substantial information/data.
