Happening to my single hand cultus 2016, done 80000 km, since a week or so, about 4 times.
Engine cranks, starts but doesn't pick race, slowly shuts down to zero rpm.
Sometimes it starts after few minutes waiting, and works perfectly normal.
It happens sometime when car is parked for just 5 minutes, or for 4 hours.
Today, not starting at all.
Nobody understands yet.
