Subject:Re: 85 Vangon revs drops, revs drops, revs drops, and then dies after a few minutes of this cycle

Sounds suspiciously like a problem I have with my '91 Carat. I haven't
tackled the problem yet - so can't say for sure - BUT  -- some of our
gurus - and especially Scott Daniel  who has had considerable experience
with this - insist that the difficulty is the throttle switch. The
settings for the thing is critical and wear and whatever can really foul
things up. This is a sorely neglected maintenance point. Nobody checks
it  - they just drive until the engine sputters and quits - then they
"holler for the calf rope!"

Good luck.
