Troy Bilt Bronco riding mower 18 hp Koehler - electrical issue - mower will start and run

Mower will start and run for 20 seconds.
When the engine cuts out, the headlights are out w/ the key in the middle position (lights/run)
Mower will not start when no headlights; replaced ignition switch - same result
If headlights are on, the mower will start and run for 20 seconds. Any thoughts?

    Should be a decal on the engine block. Ignore the family number, it is for emission purposes and of no use to us. If a Briggs and Stratton the information will be stamped into the engine valve cover.

    Kinda sounds like a bad connection. Check the wire terminals. I suspect you have Packard (Delphi) version with spring contact which can break leading to loose connections.
