I have an 05 ss/sc and recently as I was driving it randomly shut off and lost power to most systems. Discovered the fuse in the trunk was corroded (replaced and did security relearn) A few days later the car did the same thing as I was accelerating to highway speeds and the security light came on and vehicle shut off. Found a P2101 code and did a throttle body replacement and 5 miles down the road the car shut off again. Same thing security light and complete shut down. Its been 3 weeks and still have not found the cause. I was thinking it may be the BCM because of the security issue. If I let the car sit for a few days it will start, run and drive for 5 miles and shut off. I have checked everything under the fuse block under the hood and it all tests fine. Did take notice now I have no sound to my interior speakers, p2101 still present. I am at a loss and looking for advice. Please Help

Thank you in advance.
