Question about Craftsman 20 hp 42 in. Deck Lawn Tractor - CA Model
It Starts and runs fine for about 15-20 minutes then it begins to pop and then backfire and stalls. It might start again and run for a minute or so and then pop,backfire and stall. Try to restart but won't,Just cranks over. Let sit for awhile(cool off) and it starts and runs ok for another 15 -20 minutes and then dies again. It seems as though the ignition is cutting out. Almost seems as though heat is affecting the ignition. I noticed this problem come on slowly,popping once in awhile but kept running ok. At first thought it was me leaning off the seat.
I have checked the safety switches and all seem to be working properly. I even tried to by-pass the seat safety switch and it did not start. This mower is only 4 months old and is a Craftsman 42 inch, 20 H.P.Intek Lawn Tractor.
I think that your right. Sounds like your ignition coil witch is most likely located under the the flywheel cover. I know that on some briggs and stratton engines they are actually under the flywheel, just trace the sparkplug wires to know for sure. When the ignition coil beginns to fail they start slowly (spitting and sputtering) and then they get to the point to where they stop firing after getting heated up and adventually quit all together.
