Default Weird problem on start up- need help

It started a couple days ago, I would start the car but it would not turn over. The second time I cranked it, it started right up. I then pulled out of my driveway and she starts to sputter then goes back to idle then sputters again and shuts itself off. I cranked it up again and she runs just as new. I really dont understand what is wrong. At first I thought it was a one time thing until it did it again this morning. It seems to happen only when I start her up in the morning and its the same process: 1)try to start her, she wont turn over 2) she starts up then shuts herself off in 10 secs 3) I crank her again and she is fine for the rest of the day. You guys have any suggestions?

Hook up a fuel pressure gauge. I'll bet you see low pressure. May be the pump or regulator. A bad regulator will allow fuel to drain back when shut off. It takes a few secs for pressure to build enough to run the car.
