engine stops under deceleration

Hello,

so I have a problem to which I have trouble to find a solution.
I've been to three car-services and everyone said that everything seems normal. Only it isn't.
They couldn't find a solution.

Like I said in the title, engine stops when I break. Not always, just random.

I've cleaned the throttle body, i've replaced the IAC valve and the crankshaft position sensor (because I had an error that said the crankshaft position sensor is malfunctioning. the error disappeared after that).

Now I still have an error P1397, but the mechanic said it has nothing to do with my problem.

The most frustrating thing is that the problem doesn't happen all the time. Only random, and only after I've kept the engine running for 10-15 minutes with the car stopped.

Any idea for a solution would be welcomed. Thank you.

My car is Chevrolet Aveo 2008 1.4 16V. 94HP.

The P1397 code is a wheel speed sensor problem that may affect ABS if you have it on your car.
