long story of woe with hoses snipped

You have a working setup in front and non-working setup in back.
Should be simple enough to swap one part at a time from front to back
and back to front. When the problem follows the swap, you know the
culprit.

It could be that one of the brass couplings isn't fully engaging,
limiting flow sometimes. Or it could be some weird defect in the hose
that is temperature dependent even...ok when hose is hot in sun, not
ok otherwise...

Did you buy all the brass fittings at the same time/place? I've found
that they are not usually interchangeable between brands. Look at them
closely to make sure they are all the same.
