Baron,

"The issue is that the female part gets expanded with use. Simple
misalignment of the pins as they are mated and detached. They do
float slightly but nowhere near enough to compensate.

If you remove a female pin from the housing and try it on a male one
you will see what I mean.

Here is the link for the Molex 8981 power connectors

Thanks for the link! Was able to locate a few from a friend so will
give it a try.
