I am having the same proublem with an older 12 hp motor
I replaced the solanoid and the coil and it ran after that for 2 mows not it has died again -- the only thing i can think of is the points or the electronic pack try these things

I have a 12/30 and had the same problem. Check the solanoid - 2 pole type- changed this fixed my problem. Do you have a handbook?

Reveal the coil by taking the cooling cowl off. Then disconnect the cut out wire - small diameter, usually black - and see if you get a spark now. These engines have electronic ignition (no points etc) so if still no joy its likely to be a coil fault - but they are generally very reliable, I have to say. I have had problems with the flywheel woodruff key shearing though....which upsets the timing.
