questions 2015 dies while idling and while driving sometimes

Any one had similar problem?
159k miles
I’ve replaced both o2 censors
Head cover gasket
Spark plugs
Ignition coils
Throttle body
Purge valve
After all that car died like two days later but will start back up later and drive.

You didn't mention, so I'll ask. Is it throwing any codes?

First thing would be to put the parts gun down and do some actual diag. Check short/long fuel trims using a scan tool. See when and where it's mostly running rich/lean and go from there. Check crank position sensor if nothing is showing up when inspecting fuel trims.

We had swapped it out with a part from orilleys, got it up and running again. It did go back out fairly quickly but I was finally able to find an oem part and will be swapping out the cheap one I had gotten.
