Each time it want start the fuel is below a half tank? And you tow it and it starts. The first thing to do is to confirm that the reason it want start is no fuel. Do you hear the fuel pump running when it want start? It is possible that either the pump or the strainer has come loose from its mount causing fuel to not be picked up below a certain level.
In theory you are right, I had a chevy pick up were the strainer and pump had come loose and got hung sideways on the mount, i guess were it was floating at the time, and would do the same thing your truck is doing. Does your yukon have a fuel filter? IF so pull it and check it just to see if it is full of trash. If you can hear the pump running, have you checked fuel pressure?
I understand sir. Well then i would drop the filter and make sure it is not stopped up. Lets forget the fuel issue altogether. When it want crank we need to check the fuel pressure. I work on these trucks everyday and the number one issue for no start is fuel pump. So lets check the pressure
