The fans not turning on is the problem. When you are hardly moving or stopped, there is no air flow. That is when the fans need to come on. When you are moving, air flow happens from the vehicle moving. Thus, it doesn't overheat.
The first thing I need to know is if the fans are good or bad. Take a jumper wire from the battery to the fan motor to see if the engine runs. Let me know what you find.
