If I had to guess, I have a feeling it is related to a weak or failing fuel pump, but I can't be certain. Let me know about the check engine light. If that isn't on, I am going to recommend checking fuel pressure. It really isn't too hard to do. Here is a link showing how it is done:
Here is one more link I need you to read through and see if anything in it helps:
Let me know.
