Ring Pro 2 and Doorbell going off line after a few days of power

I have a hardwired mechanical doorbell with the Pro Power Kit added to it to run a Ring Pro 2 video door bell. When I test it, it acts like the breaker is tripped. ( but it is not) the door bell does not work and the Ring is offline (not getting power). Flipping the breaker does not restore power. I have to remove the Pro Power Kit and turn the breaker off for an hour, then do a fresh reinstall of the Pro Power Kit to restore activity. But then it goes out again after a few days. Any suggestions on more permanent fix? Or does Ring have a doorbell with transformer I could install in the same spot with the existing wiring? ( not a separate 120 outlet) Of course this is at a rental property in an other state, so remote actions or simple things the renter can do would be best. Onsite work has to be schedule months in advance. Thoughts?
