 Well, a couple things come to mind. The first would be a fuel pump that is failing. The second would be the fact that, you know, within the 200,000 miles, if we have worn-out spark plugs, especially if you started on a driveway and you move it and then shut it down, it's really not warmed up and there could be an excess amount of fuel within the combustion chamber. And when you let it set, it clears out and then it starts.
