No mine runs 24/7. Initially the hash rate was dropping was the only problem. If I had to guess I would say faulty power supply or power supply overheating. There are small fans inside your power supply, put your hand at the back of your asic where the silver part is. That is the exhaust of your power supply. Make sure it is blowing air out the back. If its not, your fan inside the power supply is dead. Also make sure you dont have the back of the asic up against a wall , were the exhaust maybe blocked.
Good luck
