This is most likely one of a couple issues. So, let's start with checking them off the list.
Here is a guide that will help with getting us started with this issue:
https://www.2carpros.com/articles/stall-at-idle
The first most likely issue is the idle control valve is dirty or needs to be replaced. On this vehicle this is the throttle body but here are a couple guides showing the different styles.

If this is clean and not the issue, then the next likely issue is the fuel pressure is not correct. So that means we need to check the pressure and find out what it is to know if this is the issue.
