I agree that he was probably sleeping in the open because he was too hot. My Syrian, Quigley, was doing something similar this afternoon - lying stretched out on top of his substrate for once, in the shade under his platform and between his house and the cage wall. I gave him some cucumber and he perked up. Obviously, keep his cage in a cool shaded area. If you can, put a cool pack outside of the cage near the wall and put something ceramic which has been in the fridge into his cage. Cucumber to keep his water levels up is good, too.
