This is my first post, sorry if Iím in the wrong section
I have a John Deer riding mower model 125A since 2006 and never had any problems until this spring (will explain later). Never had to do any repairs but I do maintain the tractor regularly and every winter before I store it in the cabana I winterize it properly including oil undercoating.
Last spring, like before, the mower started within the first couple of turns and I started cutting the grass but after about 10 minutes the engine stopped. Could not find the reason and trying to start again she started with no problem. It did the same another couple of times but I was able to finish my job, takes me about 1 hour to cut the grass. Then for the rest of the summer never had any more problems.
Two weeks ago I started mulching the leaves and after about 10 minutes again the engine stopped. Somehow I felt it had to do with some kind of a sensor like the one under the seat and so I put a tape to hold the sensor closed. Now she started but stopped again after 2-3 minutes. Did the same for another 2-3 times and the same happen again, she starts for 2-3 minutes and then she stops.
When I was trying to start it I noticed when I turn the ignition switch ON sometimes nothing happens like there is no battery and then when I turn the ignition switch ON/OFF a few times the engine will start. Looked to me perhaps the ignition switch went bad because when I turn the switch sometimes I can see I have power and sometimes I have nothing.
Eventually she started again and was able to finish my job and park her inside my cabana. If it was a gas problem she will never start or when the engine starts the sound will be different but no, when she starts the engine runs like new. To my opinion it must be an electrical problem perhaps somewhere a loose wire but I donít know where to look for.
