fx turn off after worming up

[fx35 KSA]

hi guys this is my first post
i have infiniti fx35 2009
1 week ago
if i start the car to warm it up every thing is normal (rpm is OK)
but if its already warmed up or after a road trip
then try to start it again it will turn off directly
so i have to turn it again and hit the accelerator pedal so it will not go off(rpm is dripping down sometimes)
im thinking about the the fuel filter or the throttle cleaning?

thanks

Sounds like the throttle bodies. How many miles do you have on your FX?
