Engine stalls

I was grading my drive for over 1/2 hour at very low speed when suddenly the engine began stalling at idle. It must be started in gear with one foot on the gas to get it to move. The manual suggests many different solutions – just wondering if anyone had experienced and solved this before I start going through all the steps. It was running smoothly with no problem, the fan was working when needed and plenty of gas.
