Riding lawn mower died while was mowing. I checked gas, oil, gas valve, and can't get it started. It has good power from battery and starter. What do I do now?

Did you pump the button thing?

Hi,
No model or brand given, or time span; but I would guess ignition or fuel pump (if so equipped) as likely culprits.
Peace,

I shifted it to choke. It doesn't have a manual pump button to start it with.
