Long distance diagnosis...
After my repair (head gasket in my Scorpion's twin cam) I drove 500 miles. Next morning I checked the coolant level in the ss tank. within 1" of the neck. I too found a single drip leak at a hose connection with a cooling system pressure tester. I too smelled coolant occasionally. After 1.5 hours of driving enough air would be in the system to cause problems.
It sure sounds like a head gasket leak similar to mine.
