I have moments were I just don't remember. I am working and I blank out. It feels like I am day dreaming. I keep working but don't remember how.

Absence. If keep happening you might have to see neurolgist to rule out absence seizure any medical condition issue with blood sugar or low blood pressure have physical exam.
Seizures. You are either extremely sleep deprived, or you need a workup to exclude what are called "petit absence" (or "small absence") seizures. See your family doc and get a referral to a neurologist.
