If you haven't tuned it up for a long time, you should check things to see if they need replaced. It is hard to say what is causing it without the check engine light being on. Without it, everything becomes a guessing game. These are things I would recommend that you check.
fuel pump pressure
throttle body for being dirty (maybe run a good injection cleaner through it)
trans fluid is clean and full
I know it seems like a lot, but any of these things could cause this type of problem.
