Car shut down while driving

My car drives smoothly and flawless, except for sometimes, usually everyday once or twice, when applying brakes or let it drive without pressing the power pedal. When doing so, sometimes it shuts down and the dashboard lights come on. Then I need to put it on (P) and turn the key off then wait a few seconds before starting it again. Then it starts normally and might shut down again or not.
If the car powered off and I started it immediately without waiting a few second then the "check engine" light comes on the dashboard. Then I need to get the car off and wait for twenty to thirty seconds before starting the car to make the "check engine" light disappear.

I have checked the both fuse box inside the car and under the hood. Everything is okay and the fuses are all okay and all of them are according to the diagram.
I have checked the MAF and it works great. I have also checked the connectors and wires of the following sensors (crankshaft, camshaft and MAF).
The only thing I have not done is checking IAC sensor and cleaning it.

The scanner tool does not give any error codes.

Any suggestions?
