Human Factors
After experiencing some abdominal discomfort and diarrhea I decided I was still feeling well enough to depart and climb to 23000 feet. After leveling off with the auto pilot engaged I started feeling sick and asked for a sick sack. At that time; according to the flight nurses onboard; I passed out for 30-45 seconds and woke up again. I diverted to another airport that was close and VFR and landed safely.
Air taxi pilot reported passing out during the flight in a single pilot operation.
