Most likely a bad ignition switch

That was my first thought too, so I went AutoZone bought a new switch, installed it. It was fine for about 2 weeks

The part I got is an ACDelco switch


What about the ignition lock cylinder did you replace that or is that what you're talking about the switch? Because as far as I understand it you have the lock cylinder then you have like an electronic thing that mates with the lock cylinder and it's called the ignition switch so if you replace the electronic ignition switch then I would think about replacing the ignition lock cylinder.
