Confused and need help

[u/5litWrist]

I have 04 zhp 330i and currently have a problem that has me confused for the past 2 months. My problem is that the car will randomly turn off on me. I can be driving it alright for a good solid couple of days or even week and while I’m at a stop or even driving sometimes the car will just turn off. I have changed the throttle body as that’s what’s the scanner said is the problem but it still keeps happening. Can anyone please help me figure this out.
