Why does my 2007 Chevy Tahoe shut off

I have a 2007 Chevy Tahoe that shuts off within the 1st 5mins. I don't really warm up in the mornings. When I pull out of the drive way I accelerate to 15- 20mph. (I drive slow through my neighborhood) As soon as I let off the gas my RPMs drop and the Tahoe shuts off. My car won't shut off if I've been running it for a while. Its only within the 1st 5mins of it sitting for 5-6hrs straight that it does this. I took my car in to AutoZone and they said it was my throttle sensors. I've replaced both throttle senors (the one on the engine and the one on the pedal) and it still shuts off. Can anyone recommend something else

    Colds start problems are not usually throttle sensors, but throttle body, vacuum leaks or low fuel pressure.
    Air filter been replaced?
    Cleaning the throttle body may help. If the plate isn't closing all the way, it can cause similar symptoms.
    Engine warning/Check engine light on?

    Dirty MAP/MAF sensors can cause similar symptoms too.
    Idle air controller is also another culprit that can cause problems.
