Can you please give us more information on what is going on? Does it do it more when hot or cold? What things have you checked? To me is sounds like you have a vacuum leak or a weak fuel pump, but is can be bad gas or the engine needs a tune up. Here is a video to check for the vacuum leak and a guide to help us as well.
