Craftsmen Riding Lawnmower with Kohler 15 hp engine runs fine, stalls after 10 minutes, won't restart until 2 hours later, then cycle repeats

I replaced the carburetor on my riding lawnmower after gas was leaking from it. It started just fine, but then after 10 minutes of using it, it stalled rather quickly with a single backfire. The engine was hotter than normal. I pulled the spark plug out, connected it to the ignition module and held it against a bolt head and it looks like it is not getting a spark. Could it be the ignition module? Or is the engine too hot perhaps because of lack of air flow (my air filter is looking dirty)?
