With the use of the word "valve" (singular), that implies that you have a 1 valve winterization setup...which requires a check valve in the line out of the water heater. Since the water flowed OK, and the suddenly stopped flowing, a malfunctioning check valve is a possibility. I would open my hot water faucets, and gently tap on the check valve to see if it frees up. Hitting it too hard could break a line and burn you with hot water, so be careful.
