Go to Advance or Autozone and borrow a fuel pressure gauage. When you have the problem again, hook up the gauage and see what kind of pressure you are getting. My guess is that you have an fuel issue. I would also clean the MAF sensor. Is your check engine light on? If it is, have you read the codes yet?
