Shifting after start up problem

[k_checo]

Just recently I replaced my old broken down f22 for a new one with 65k miles. After starting the car up after a long breezy night and letting it warm up for a while, I begin to shift the gears to move the car out the spot. As i do this the car shuts off and then Ill have to try it all over. What I have done to avoid this is press on the gas pedal (while in idle) after the engine has warmed up quite well and this eliminates the problem. What can be causing this failure? I know its not normal
