Have you changed the motor oil. Checked the transmission oil, And tire pressure? All these things will put more strain on the engine and make it heat up faster, Is there any rattling noises coming from th engine? Is the cooling fan working? How many miles do you have on it? Is it leaking coolant. Hoses wear out after time and leak and will cause over heating. Also check the radiator resevior. Is it full? And does the cap vent properly? If all else fails take it in to a trusted mechanic and have them check what codes its throwing with an obd reader. When the check engine light comes on it will not tell you exactly what to check. Sometimes visual inspection will do. certain conditions like yours require a scan tool. Good luck.
