I think you should work through the details with your team and own the project and defend your decisions. He can only humiliate you if you believe what he is saying. There are people you just can't please, however, that is how he is pushing you to be great. That is probably why he is successful.

To be honest I have never received even 4 hours per week from a manager, on a consistent basis. You need to manage him like he is upper management or a client, he will ask the impossible, not tell you how to succeed, and expect everything.

Build what he needs, and persuade him as to why it is great. He wont express the details because even he doesn't really know.
