Hi Jeff, I can see others have said the same thing, but I'll add my 2p worth - it's your APP assembly that is the problem. Not likely to be the K3 end (but possible), it's the cable end and there is one major cause: 

The contacts have not been pushed completely home during assembly. 

If the contacts have been soldered, it's possible the solder has spread across the contact in such a way as to prevent the contact being pushed completely home.

Never had a problem with the cable pulling out of the K3s APPs and not had to secure it in any way.

I have been using APPs for ALL my 12v gear for > 6 years now, with no problems at all - all contacts are crimped, not soldered (once you've decided to go the APP route, buy a really good crimp tool). I replaced the intermittent molex connector on my FT-857 with APPs and stopped all the problems with the rig cutting out use. That rig was moved from a base rig to a portable rig and back again every week and I've never had a problem with the APPs.
