Based on the symptoms you described, it appears that there may be an issue with the powertrain control module (PCM), fuel pump relay, or the diode in your 2008 Ford Mustang 4.0. The overheating of these components and the blinking of the overdrive light before the engine turns off indicate a potential electrical problem. I would recommend having the vehicle inspected by a qualified mechanic to diagnose the specific issue and determine the best course of action.
