When the squash is forming and gets about 2 inches long it is turning yellow...any idea as to what is causing this?,,,thanks

Your female flowers are not getting pollinated. Do a search on "hand pollinating squash", and you should see tons of posts about it...

Definitely sounds like it could be a lack of pollination.

I go out each morning and look for new female blooms, the ones with the Zucchini growing.
When there is a fresh female flower opened up I pluck a male flower, NO Zucchini, peel back the pedals get it freaky with the female.
