Eye of the Moon reads "Eye of the Moon (Su): Your connection to the moon makes you supernaturally perceptive. You gain darkvision to a range of 60 feet. At 11th level, as a standard action, you can focus on a specific object or area (the size of which can be no greater than a 10-foot-by-10-foot square) and see it as though with true seeing as long as the moon is shining on it. Moonless nights, cloudy skies, and shadows interfere with this ability."
Do I lose the entire ability without the moon, or just the true seeing?
And if possible, is there any backing to a ruling, since my GM just decided to switch his ruling on me.

The first section makes no mention of only working in the moonlight or only when the moon is out, so the 60ft Darkvision will work regardless, the true seeing portion however has the stipulation of needing to be touched by moonlight. (just as a note, the Darkvision would naturally need to be used only in dark places where Darkvision would normally work)
