Cuts off when driving, randomly, will not start again for hours. I had the fuel pump replaced and it worked fine for 2 weeks then it did it again. I had the idle air control valve replaced and ran great for 2 months then did it again. I had to have it towed home each time. This last time after having it towed home I ran battery dead trying to start it for over an hour. Charged battery and still would not start. The next day it cranked right up. What is the issue?

There are many things that can cause this issue, but I have seen the crankshaft angle sensor become weak and cause the engine to stall much like you have described with no trouble codes. The key is to find which system is failing, either fuel or spark. Please go over this video to see what I am talking about:

Here is the location of the crankshaft sensor so you can swap it out if "no spark" is found. Check out the images (below). Let us know how it goes.
