The common peoblem with these types of heating devices (coffee makers etc) is that the female portion of the plug gets hot over time and becomes loose. As it gets looser in heats up because of the bad electrical connection. Your only option is to buy another plug and cord. Attempting to repair is not feasible, and can actually have negative effects, like causing a fire or a electrical spark. You can find a lot of replacement parts on line by goggling your model number. Good luck to you....
