overheating when I driver over 20 minutes ?

What is your question?

The noise come at the driver seat side under the hood when it come to the red light or stop sign the engine stall suddenly and stop completely! So I reverse to parking and start again it crank it up , but the dangerous thing is when you slow down and turn your wheel , you don’t know the engine is already stop that make it very danger to hit other vehicle and accident happen , these thing you can prevent it

What makes this problem better or worse?

Better when it cool

How long has your 2007 BMW 328i had this problem?

Since last year already replace water pump and thermostat
