Dave, from your description, everything sounds normal.

My external cooler fan (180°F turn on) usually runs down when I turn the key off unless it is quite cold out. 10W40 oil and the oil temp sits around 200°F when running.

The carb shwoosh after 5 - 10 minutes sounds like percolation in the float bowls as someone mentioned. The bowl liquid rises in temp as the engine heat soaks until it suddenly boils and the rapid evaporation of the vapor cools the bowl and carb off, stopping the boil There is usually enough fuel left in the bowl that it should start right up.
