Something's getting hot and causing it to stop. I don't think changing cooling parts would make a blind bit of difference.
When it stops do you still have a spark???

Get it on diagnostics, it's the only way to go by keep throwing parts at it causes frustration and expense simples

Diagnostics will tell you.
The 02 sensors kick in when the engine is hot, & these would be the first thing i'd look at.
