Have you checked the fuel pressure? Make sure the fuel pressure is fine
at idle then watch the pressure gauge as you get to where it sputters
and dies under load.

There is very little fuel used at idle so a weak fuel delivery system
can idle fine but be unable to maintain the fuel supply under load. You
can watch the gauge while you add a load but a proper pressure/quantity
test should be done too. About $10-20 for a cheap gauge and there is a
place in the engine compartment where VW provided a pressure test hose
connection. This is all simple to check, only a screwdriver and some
extra fuel hose are needed in addition to a gauge. In a pinch you can
use a tire gauge of the type with a dial and hose.
