Replaced Coil - Ran Great, then hard shutdown 5 mins later

[tankmcnamara]

This is a Briggs 120212 0360 E1 6.5 HP engine on a Troy Built tiller. Replaced coil. Tested and confirmed firing plug. Engine started right up. Ran for about 5 mins the died - suddenly, just like when you would turn a switch. Carb still getting fuel, but now no park again. Disconnected kill wire. Still no fire/start. Is there some other electrical component to this engine I am overlooking that is killing the ignition?

Thanks Mark. I overlooked an important detail in reassembling. When I installed the new coil, I inadvertedly wedged the ground-out wire between the throttle assembly and the engine block. So when the block heated up it melted the insulation and then the bare wire grounded out the coil.
