A/C works every day in the morning. Sometimes it works all day. Yesterday I drove from my house to a restaurant and the A/C worked fine. I went in and ate. When leaving the A/C didn't run at all. This morning the A/C worked just fine. Fuses are fine. Seems to me the A/C quits working when engine compartment gets hot.

So, when you say the A/C stops working do you mean the air is not cold or there is no air coming from the vents? If there is no air coming from the vents it sounds like the blower motor may need to be replaced, if there were no cold air, I would check the refrigerant level. here is a guide to help you see what you are in for when replacing the blower motor with instructions below to show you ow on your car. Also, here is how you can check the refrigerant level video as well.
