I think you meant to post that last visitor message to the Sedona forum rather than to your own Visitor Messages. From what you've shared of your symptoms, this sounds like a rather classic description of a failing fuel pump. With use, the fuel pump heats up and then either spins too slowly, or not at all, when shut off for a short period of time. After it has a chance to cool, it works again sufficiently to start the engine. This assumes though that when it doesn't start, the starter motor still spins the engine over. You don't fully describe what you mean by "will not start." If the starter spins the engine but the engine never fires off, you can test the fuel pressure theory by spraying some starting fluid, throttle body cleaner, or similar into the intake and seeing if the engine will fire off that way.
