Default strange engine hesitation

Hey im kinda new to this whole thing....I purchased a 03 a4 1.8t a few months ago.... i recently noticed that if drive the car and turn it off for a minute or two and start it up..it starts up fine...but if i leave it sitting for 20 minutes or so and then try to start it...it starts kinda ruff....it takes a second or two before it catches itself...does anyone have any ideas on what this can be???

How old are your spark plugs? Coil-packs? Version?

Default Any mods done recently? Any hesitation when accelerating when the engine is cold?

Is the "cranking longer than usual" only happening when the engine is warm?
