Mespe, sorry to say but either your ignition module or ETA is starting to fail. Your ASR could be as simple as replacing the brake light switch or replacing the speed sensor on your rearend. Anyway the lose of Cruise Control points to the speed sensor, ETA and ignition module not working properly. The engine compartment can get extremely hot and cause damage to part because of heat.
