Only thing I noticed that I did differently was stepping on the brake pedal lightly (half way) during the engine start. Engine cranked for 10 seconds

After that incident, I always depress the brake pedal all the way (floor it) before pressing the engine start button.
I think if brake pedal is not depress all the way, it will not supply fuel to the engine or something in the electronic control system prevent the vehicle from starting.
I never had that issue since (5 months - 4k miles).
