have you checked coolant level/condition?

sounds like a cat failure ,blocking the exhaust therefore temp will go through the roof.
exactly what i went through when mine went. no power except to get off the motorway and pull over ,even had to put heater on full fan speed to get temp down .might be worth a look.
