Answer: Based on your description I am not certain what is happening to your mint. In a container, it will do best with sun all morning and afternoon shade. Afternoon sun would be too intense for mint in a container. If it is in a container, it may need fertilizing and more evenly moist soil. Top dress with a good quality compost and use a water soluble fertilizer such as 10-10-10 plus minors. Follow the label directions for how much to use. Water as needed to keep the soil evenly moist, meaning damp like a wrung out sponge. You would not want the soil to be sopping wet or dried out, just damp. If it has become very crowded in the container you might want to repot it into a larger one. This will help with keeping the soil more evenly moist and will insulate the roots better. Also, if you have not been harvesting regularly, you could try cutting it back very hard to stimulate fresh new growth. I hope this helps!
