There are few reasons for this to overheat in the manner you are describing.
It could very be the thermostat, however when you have a stuck closed thermostat the temperature will keep rising until something catastrophic happens unless you shut off the engine.
You could also have a issue with the cooling fan. Check to see if the fans come on.
A non functional fan can be the cause of a faulty motor or relay. The relay is located in the junction box under the hood (see below for diagram).
The relay can be tested.

Another possibility is a faulty water pump. If the water pump does not cycle coolant thru the engine it will overheat as well.
I have attached the fan and water pump replacement diagrams for your reference.
Please let me know of any questions.
