Well I am in a process of a limitation bled cooling system maybe it is a sensor as it corrects itself soon after I lose power.it happend today on a hill but soon resumed power.if this is a sensor where will I find the offending one to clean check.already been advised that there is a sensor that will send a message to ecu to cut power if it sences the engine is hot.that advice was from on here my thanks for that.dont see how it would cool quikly if engine was to hot.
