This sounds like an absence seizure. I'm putting some links below and I urge you to see your doctor right away and see what, if anything, can be done.
Absence Seizure
Atypical Abence Seizures
Simple Partial Seizures
Complex Partial
Seondarily Generalized
That's start for you to see how close they are to what you're experiencing. I recently wrote an article on types of seizures so that was the first thing that popped into my head when you described what you feel.
