Shot gun sounds like he has the solution. I did have an older JD tractor the the board went out on also. The new board was beefed up a bit, capacitors/diodes or whatever. So they must have been having problems with the old ones. This was way past warranty so customer had to pay. To make matters worse, the owner told me he thought it was the coil & purchased one and told me to change it. I told him, who said it was the coil but he insisted. Well, needless to say, dealer wouldn't take it back. I even said I didn't install it but they won't take back electrical items. I believe it was in the neighborhood of 90.00! Thinking back, after the tractor ran awhile, the circuit to the fuel solenoid would fail, shutting off the fuel. This wasn't a spark issue but that may be another module/circuit board. Although shot gun says "they will be very happy you took the inititive to check into the problem." I would call them first & tell them what you suspect & can you bring the module in for them to check. Some places will look for any reason to void the warranty. Not all sales people are like shot gun.
