Long title, but intermittent battery failure during ignition. Turning to run, the dash lights up. Go to crank, everything goes black. Total power failure. Usually works after a door slam, banging on the steering wheel or closing the hood. Wiring issue? Fuse?
The battery, starter and alternator all check out good.

Did you pull codes? Do you have a 2.4 or a 3.3l engine? As I understand your post, car is not cranking but you're doing all your screens go black. When you so trying to crank it, door the screens come back on? It could be a loose battery terminal, make sure they're tight. Could still be a wiring issue; jostling the vehicle could cause to opens ends of a wire to make connection. Does car cut out while driving?

Doesn't throw a code
2.4L
The whole car is dead and stays dead until one of the previously mentioned actions happens. Then, everything lights back up and resets.
Terminals look great, took off and retightened each. Again, battery tested good.
Does not cut out while driving. From cold start only and sometimes if making multiple stops.
@andrewpapke personally I'd be checking the ignition switch and the wiring around it... sounds like something might be loose and when you perform percussive calibration (whacking the stupid thing) whatever it is makes contact again.
