My LX 188 just stopped running "when" I was mowing, plenty of gas, Battery fully charged, oil was recently changed, cheched the fuses at the ignition board. I turn the key, nothing happens, no dash light,no sounds at all. My head lights work, hour clock is working. I have not manually tried to turn the motor yet (to check if it sieze up). I also checked the seat safety switch seem to be fine. Would love any help, Thank you
