When this happened the engine would not restart until the temperature came back down to under 160 degrees. Just some thing to think about if you every have the same issue.
I you had problems starting when the gauge showed 180, check your ECT- if its resistance is higher than what should correspond to any temperature, the engine will run rich. If this happens again, open the throttle a bit and see if it starts- if it does, a bad ECT is almost a certainty.
