Glad you found it so quick. Have a 112 that was acting the same after working about an hour. If I caught it on the first cough & dropped the clutch & idled down it would recover for a few minutes, then do it again. If I didn't catch it, it would die & not restart, no spark, unless let it rest half an hour. Last time it died it wouldn't restart at all, winched it on the trailer & hauled it home.
Coil dead. Went to parts store, got matching coil. Turns out previous owner had put on coil that needed external resister. Went back for a NAPA IC 14 SB coil, no resister needed. No problem for 10 years now.
