The problem does seem to be the backpressure... but its strange.

When I first turn it on it will work for a good minute or so, then it
will start going into "struggle mode" for a few seconds, then it will
go back to normal. It will alternate between the two states for awhile
and then it will just settle at "struggle mode".

Struggle mode is when its RPMs lower and it doesn't pump enough (bad).

Your motor / pump may not like running at the rpms and pressure you have.
Are you trying to build "The Time Fountain"?

If you deliver less than the needed pressure your system won't work. If you
deliver more the motor / pump won't like it. That's why you need a relief of
some sort - a spring loaded valve or similar.
