There is an outside temp sensor, but it has no effect other than on the HVAC system. If you can determine the cause for the no start, you will probably resolve the rough run. When it won't start, check for spark at 1 or more plugs, and also check fuel pressure. It is a bit peculiar that it will start to run rough as the temperature outside reaches 75, as the vehicle would be at operating temperature. I am assuming when it don't start, it cranks and does not start.
