Don't know if you have thought of this, but a catalytic converter that is
becoming clogged could do this.  You didn't happen to notice a rattling
from under the car prior to this whole episode starting did you?  It could
be that for now, when you turn off the car, the broken pieces are settling
down to the bottom and then when you restart, with the force of the exhaust
they work their way back into the flow.

I actually had my cat get clogged on my '86 GTI that I used to have.  It
got so bad that I couldn't keep enough revs to run in 4th or 5th gear.

Anyway, just a though FWIW.
