If the engine temp is over 190 when the engine is turned off it won't start back up until it cools down. It will start for about 5 seconds then shut down, you have to wait a few minutes and keep checking the temp, once it cools down it starts up just fine. The fan turns on at 204 and off when it's supposed to. I have noticed that when the fan turns on the engine stutters briefly like it needs more electricity. Any help is greatly appreciated.
