What is the static voltage of the battery engine off? Load test it as well. (DVOM on the battery, crank the car over and see what it drops to under startup).
It sound like the IPC lost communication with the car temporarily. If you have tech, you can drop codes throught that, just press radio buttons 3 and 6 simultaneously, until the system enters bezel diagnostics, and follow the prompts to "read dtcs".
