OK, this is making me crazy. The engine runs great and then it's like you just turned off the key. If you let it sit for about 10 minutes it fires back up and runs fine till it decides to die again. It has the early electronic ignition with the orange box. I have checked the wiring and changed the coil, same problem. I have also been experimenting with different carburetors, not for the shutting off reason but for performance reasons and it does it with all 3 carbs. Suggestions please.
