2002 Sierra Sputtering

I have a 2002 GMC Sierra. When it is cold it will sputter on acceleration at an idle it runs perfect. After 5-10 mins it runs the sputtering goes away. What could be causing this?

Take a look at fuel pressure, and check your intake gaskets for vacuum leaks on a cold start first thing in the morning.
