Sorry not an answer but I have the same problem. I started in first time after winter - it fired ok (so was impressed) - did some mowing switched off and tried to start it abt 30 mins later - NOTHING...
I replaced the battery with my car's - still NOTHING.
Does anyone know if it has a starter motor or an alternator? If so , any manuals on how I can remove and replace....
