128000 miles. It's still a pup. Last year it ran like a champ. Then sat unused over the winter (but I put StaBil in the tank, and started and ran it for half an hour every week, and charged the battery once a month).

The engine starts every time, and idles smoothly, quietly, and at the correct speed every time. So I'm pretty sure it's not an ignition problem. And for sure no plugs blown out.

My working hypothesis is that the fuel pump runs only during the brief period for a couple of seconds after the key is turned from OFF to ON. Just enough to pressurize the system so the engine starts and idles for a couple of seconds. Then the pump doesn't run any more, and that's why it starts misfiring and stalls out.

Anybody have any insight into questions 1 2 3 ?
