while ( true ) {} ; // Will not be executed

I had to remove this while(true) to allow the device to continue after shutdown. It is possible that something else in my setup is causing the cpu not to shut down - like the stlink that is plugged in. But leaving it here for others that might encounter the same issue.

Strange, because the shutdown should cause a reset after the sleep period. So it looks like your device does not handle the shutdown well.
It has nothing to do with the ST-link. Mine is always connected during my tests. The power consumption drops to about 4 mA during shutdown (probably caused by the USB chip on the board).
Note that during sleep, flashing with ST-link will cause some problems. Press and hold the reset button, start the upload and release the button as soon as the LED on the ST-link starts to flash.
