2022 Lexus GX — check-engine light turned itself off — still scan it? — buyer question from Salt Lake City

If it were in my driveway, capture voltage while the 2022 Lexus GX is actually failing — after it restarts you've lost the clue. Save the big job until that test fails. This is from a 2022 Lexus GX in Salt Lake City with 39,500 miles. Any freeze-frame data saved? Not trying to scare you — just skip the expensive first guess. If the story changes I'll post the new data.
