Thanks, Oscar you may have the answer. I have been adding carb cleaner recently and a piece of the foil top may have come off. It would explain the "instant" correction when the engine goes dead. Fuel backflow when the pump shuts down may be pushing the blackage back into the tank. Thanks all.

: I also had a similar problem a few years

: and looked inside the tank and saw a
: piece of round paper gasket that may
: have come off the top of a dry gas
: bottle. It was covering the hole that
: leads to the fuel line.

: I'll check it thanks. 2 thoughts make
: me
: think it may be something else. 1- it
: just started after using my car as a
: daily commuter since the fall of 08. 2-
: The car restarts if I am in a coasting
: stall on the highway and restart, the
: power is fine for the next duration of
: my commute of another 10 mins. or so.
: Is there a way for the vacuum to
: instantly release when the engines
: stops?

: Many things could cause this but one of
: the first things I check with these
: symptoms is to make sure that the fuel
: tank is venting properly. A simple way
: to check is to drive until it starts to
: crap out, and then quickly pop open the
: fuel cap. If you hear a swishing sound,
: and it restarts & runs properly for
: awhile, it is not venting & is
: building up a vacuum as fuel is burned
: off, increasing the load on the fuel
: pump.

: I have a puzzling issue with my GT6
: Mk1.
: Car starts fine, runs with good power
: until about 10-15 mins of fast highway
: driving. The engine then loses power
: and running at a top speed of around 60
: mph. In neutral, if I take my foot off
: the accelator the car stalls. It is
: easy to restart and then runs perfectly
: for the rest of the trip. Any
: thoughts? I changed the fuel filter
: thinking "ping pong ball"
: problem- no luck.
