PATS Security Access Denied

[Freefaller76]

So I was working a ABS/TCS issue on a 2013 Sport and after disconnecting and reconnecting the battery I was greeted with a no crank condition. Lots of troubleshooting later and I've found PATS to be the issue. No problem, break out Forscan and reprogram. However, I cannot gain timed access to do anything. After 5 minutes, the BCM/PCM "shut down" resulting in lots of codes, warning chimes and a blanked out odometer. All of which resets when the key is turned off/on. Then approx 5 minutes later, same thing...complete with BD10D7 code.
Has anyone seen an issue like this?

Welcome to the Forum.
Although the thread title seems somewhat familiar to me, I was not able to find anything similar when using the 'Search' feature.
I did find some threads with different codes related to PATS issues.
