Sometimes when I start out, after idling for a long time, I notice that my
power drops right off and the engine is having a hard time idling.

This generally is noticed just after starting off and driving to the end of
the street where I stop at a stop sign.

If I give the engine a few revs and drive off, all is OK in a few moments.

Anybody have any ideas what is going on?

It is a 1986 VW Jetta Turbo diesel.
