Warm Start Up Issue

I have a 2011 E92 335xi N55 6MT. Whenever I start the car cold it starts right up no issues. Whether its been sitting overnight or parked for a few hours. However if its warm (Oil Temp 200-240) and I turn it off and return a few minutes later it cranks for 2-4 seconds which is embarrassing. Is it the HPFP? Can it be replaced under warranty?
