non-predictable front shifting?

Tripple chainring...
-Last 2 Months...shifts fine.
-Monday evening rainy group ride...approaching the big hill, shifted to small ring great, no problems.
-Wednesday afternoon, beginning a hill, took literally 5 minutes of shifting both front and back. To various gears before it finally went to the small ring.
-test ride 2.hours later...shifted to small ring on first try.

So what's going on?

It was the higher tension on the chain that made it perform that way. You were probably cranking up the hill instead of spinning up it. I'd say your FD isn't 100% tuned properly. What model derailleur and model shifter is it? Could you give a photo of the FD at a perspective from the cassette, along the CS and to the crank with the FD on the middle gear and RD on the low gear? (Looking through the FD)
