Why does my car turn off and then I change my relay and it turns back on

What is your question?

It happens every time I run the car for like 10 minutes, I feel like it has to do with pressure. Everytime I change the relay it last for a little bit more time and it shuts off again

What makes this problem better or worse?

It’s worse when I run it for more than 10 minutes

How long has your 2011 BMW 328i xDrive had this problem?
