Sounds like a typical SU fuel pump to me.
So you did not punch the right rear deck when your fuel pump quit the
first time? A sharp punch is the first option, second is a small hammer
on the fuel pump itself, third is a big hammer. If that doesn't fix it,
then you should clean the points, if that doesn't work then buy a new
one.
95% of all SU pump problems are dirty contact points fixable in about 5
minutes with the pump out of the car. (of course it takes 1/2 hour to
remove the pump from the car)

It could be just a spacer spring on the rocker arm. They do slide back
and forth just a bit. Or low idle low oil pressure making the rocker
more audible.
