Check to make sure the cooling fans work, there's a cooling temp sensor and a relay that turns them on

You just described the symptoms of a early head gasket failure. Some on here will or like to say no do not tell him that it is probably this or that but this is in fact the exact symptoms I had for months before it finally started to blow white smoke/steam out of the tail pipe and started t miss a little then ran hot more often and later got harder to crank.

For your fan isn't running it is #getting hotwhen it stopped because no air is passing over the motor it is not overheating on the highway because you were going 60 miles an hour and air is flowing over the motor check to see if your fan is kicking on
