died and wouldn't restart for several hours. Cranked well. in hot weather.

What is your question?

Had ran it 45 mins. was hot out. no symptom till I started up a grade. Wanted to stall, like out of gas...pulled off road and it idled ok...sat a few moments. Put it in gear and it died. Would crank but not fire. Had to tow it. Next morning fired right up..Idle is a we bit rough.
