Hard start when warm

So ive got a 225 slant 6. Starts real easy in the cold, and easy if i let the car sit for 30 minutes after a drive, and starts easy if i kill it at a stop light. BUT, if i go into the store and im gone for 5 minutes or so, it takes several seconds and a small prayer to get it started. Thoughts? Weather doesnt seem to effect it.

Also, my blinkers, defrost fan, and radio seem to have quit working, but my lights all work. Can yall tell me where those fuses may be? Its a 72 swinger
