Any CEL's popping up? And could be clogged injectors. Run some fuel system cleaner through it. Also, has your throttle body been cleaned recently?

It sounds like it could be a fuel quality issue. How long has this been happening- more than 1 tank of gas? If you think back to when it started was it recently after fueling? I have seen excessive ethanol do some nasty stuff. There are some companies that make products to specifically combat ethanol and water or even stale gas. May not hurt to try.

I'd suspect electrical problems somewhere.
