Simplicity Broadmoor Hydro 14 Model 1692279 Sudden Shutdown

Mower shut down unexpectedly last time I mowed grass with no warning. After about a half hour I attempted to start it; successfully. One week later same thing happens but no restart. Any thoughts from the forum?? Thanks in advance for your ideas.

First thing would check is spark. You may have a coil breaking down when it gets hot.
