Default sputtering when cold started then fine?

I started the car and it seemed to idle a tad bit rough. When I backed up and accelerated I noticed it was sputtering real bad. Almost as if it was getting gas, then it wasn't. It did this for about a minute until I took it onto the main road and took 1st & 2nd to 5000RPM's. From that point on it ran perfect.

What can cause this to happen? Checked for squirrels and there aren't any. Any other ideas?

Does anybody know why this happens?

I was wondering if maybe tt could be a bad fuel filter, or maybe the plugs need to be replaced.

The only thing that confuses me is that it goes away after a few minutes and doesn't come back again. That's the only thing that sways me from thinking the two solutions above is the fix. If it was a fuel filter or plugs it would be a constant shudder, and wouldn't go away when the car warms up.
