I checked the OBD2 with a scanner -> no errors recorded, all ok
I swapped the key (no battery) -> same result, same problem
If you leave the ignition off for 20 mins you need two attempts to start, if you switch off for less it starts immediatly.
As far as I know the electronics go 'asleep' a few minutes after the ignition is turned off. Could it be related to that?
