the symptoms you have are most likely fuel related, as in a faulty fuel pump or the circuit in control board that powers fuel pump. We see a lot of this in our shop, and especially when ambient temps get higher. to accurately diagnose, you have to run unit until it shuts off, then determine if voltage to pump goes away (bad control board) or pump just quits pumping when it gets hot.
After it quits, the indicator light on the switch is still there. I'm going to try to switch out the fuel pump this weekend. Wish me luck, lol.
