Thank Lamolliever, I think my issue is going to turn out to be tail heavy.

Butch,
I think your issue is that there's not enough relative incidence between the wing and the floats. If it's a flat-bottom wing you want at least 2 degrees. If it's symmetrical or semi you want more maybe 3 to 5. I've seen many float planes behave as your does and increasing the relative incidence cured 'em all.
BTW, I looked at the GP floats on their web site. Shouldn't be too hard to move the floats fore an aft but I'll bet they're close enough.
