No start, computer keeps giving brake safet switch error
 

I am at a loss with this thing, xt2 slx54 2019 edition with the push button start.

Had to replace the entire computer start module and the mower ran perfect on the first try. Second try it did not start and gave me the brake switch error. Replaced both NO/NC switches and ran continuity on every wire across the circuits from the rear switch through to the computer plug which checks out but it still wont start even with jumping the circuits even gone as far as removed the entire harness to test. I did have a PTO issue where the blades would randomly shut off (pretty sure the belt was slipping) but since I can't start the mower, I can't test that theory. Was only able to put .8 hrs on this new start computer before it gave me the code. I've ran through the wireing diagram that I found and everything and simply can't figure this out. I would greatly appreciate a point in the right direction.

I would test your battery. My understanding is a low voltage battery can cause the PTO to turn off while the engine still runs. Your key button (computer) may be acting up due to low power/voltage as well.

Charged the battery overnight computer showed 13.3 volts and I still have a no start condition due to the brake switch error.
