I'm also wondering if it restarts right away when it stalls or needs to cool down first.
Customer: replied 1 year ago.
I found out that he also changed the ignition switch it would not restart until it was cold no longer has to be cold since ignition switch changed, the only code that comes up says theirs a problem with the o2 sensor

It is going to be hard to figure this out 3rd person but if vehicle stalls when it warms up then it sounds like problem is most likely fuel related such as a failed fuel pump. A easy test is to see if it runs on starting fluid during problem, if so this is a strong indicator of a failed fuel pump. Let me know how it goes or if you have more questions, thanks.
