Electrical issues
Have a 2005 C6, having many electrical issues. When driving radio shuts off, all gauges go to zero, all warning lights come on, windows don’t work, doors will not open, car continues to run but once it’s turned off will not start again for sometimes 1 day, sometimes 2 weeks and then it starts like nothing ever happened and everything is fine. Then it’ll happen all over again. Been to a couple repair places, with a couple things repaired but then when I take it home it happens all over again and the repair shops cannot figure it out.

I had a battery fuse blown on my truck that caused symptoms like that - although I was also charging the battery in between starts as there was a battery voltage error as well and the battery was killing. If your battery is staying fresh then that won't be it.

You don't say how long you've owned the '05 or whether the problem has existed all along or started just recently. In any case, start with the basics....check all grounds, especially engine to chassis; check all power connections especially at the battery & starter motor; check health of battery. Sometimes it's simple things that cause the gremlins you're experiencing.
