Hi bobtribe,
It looks like your theme or another plugin is also attempting to use the Google Maps API at the same time (which can cause problems):
Warning: you have included the Google Maps API multiple times on this page. This may cause unexpected errors.
The first step here is to figure out which other component is doing this. Can you deactivate all other plugins and switch to a default, unmodified theme – confirm this is not a problem under those conditions (but let me know if it is) – and then start reactivating everything, testing at each stage to see if the problem has returned?
Thanks!
