yamaha T-8 stopped running

  My '05 Yamaha T-8 shut down after a couple hours of trolling.It seemed as if someone had reached and hit the kill button.I checked the oil level in case there's a low level cutoff.I looked at the kill switch and wires.They look OK.There's no spark at either cylinder.I doubt two coils would die at the same time.I thought I'd ask if anyone had some experience before I dig in.Thank you.

Thanks Milemark.Upon further inspection,I see one coil does fire both cylinders.The orange wire to the coil is hot when cranking.

I would check the obvious,like fuses and visible connections.But yeah,a coil pack can drop both cylinders.
