Maybe your radiator fans are not coming on. When you stop you lose all the air flow through the radiator and the car over heats.

Thanks for the answer. Had a feeling it's deals with air flow. Because while I was driving the temperature gauge dropped when I was going about 40. And went up when I stopped.

Check the fuse first and if that is good it might be the temperature sender or the relay.

For testing purposes unplug the coolant temperature sensor and start the engine. The check engine light will come on because the sensor is unplugged. Ignore it. The radiator cooling fans should come on immediately at high speed. HTH. -Jim
