Umm.... If I am to take this literally, that means that the starter isn't engaging the engine, which I assume is not what you mean. If you do mean this literally, than the diagnosis is a bad starter solenoid or bad wiring to the starter causing insufficient current and voltage. But I think you meant to say that it turns over, but does not fire, is that correct?

There are many things that could cause this, and I could irresponsibly pick a part and tell you to replace it, but that would be easy and wrong.

In my opinion, your symptoms are good cause to conduct a fuel pressure test, or multiple tests under different circumstances.

My instinct tells me that this is a fuel delivery issue, and because there are so many iterations of that (pump, filter, injectors, etc..) you should first confirm that you are having a fuel delivery issue, and under what circumstances.

Also, just to rule out a plugged up tank venting system, try opening your gas cap next time this happens and see if it "cures" the problem.

What I am getting at is the diagnosis is: tests. You must conduct tests to figure out what is wrong, and fuel pressure is a good place to start.
