I'm pretty sure i have an electrical problem. I can mow for a few minutes and the engine just dies. Sometimes it will start right back up, sometimes i have to wait a little while. I have changed the fuel pump and cleaned the carb. I was able to move the shroud back enough to remove the coil and clean where it mounts and also the flywheel magnets. I clipped the wires on the seat safety switch and taped them.(i'll reconnect later) Still the same problem. I want to move the shroud back and disconnect the wire that grounds the coil through the safety switches to see if the coil is bad but i don't know which one to disconnect.(there are four wires besides the high tension wire that goes to the coil) If someone could direct me to which color wire to remove i would sure appreciate it. Thanks Chuck
