Water in the carbs can cause this. A slug of water lies in the fuel
transfer passages in the carb - when it gets sucked up to the
metering needle, it blocks the jet, as water will not go through the
same small hole as gas will. When the engine stops sucking so hard,
the water falls down, letting gas through. If you get the demand
high enough, the needle is high enough that fuel flows around the
water, but it still leaves the water in the bottom. (on HS carbs
with clear transfer tubes, you can actually see this happen) Easiest
thing is to dump a double dose of DriGas or fuel system cleaner in
it - the cans are usually for 20 gal, so a whole can is about right.
The cleaner may also remove varnish etc on float and metering
needles.<br>
Your comment that the filter is of unknown age but is OK is wishful
guesswork - change it. And when you remove it, bang it on something
with the inlet end downwards - see if any water comes out. Water
does not go through good filters easily, but it can under some
conditions, and it only takes about a half cc to block the jet as
described. <br>
(banging the filter like this can get you home when water blocks the
filter too. In winter, a little water will freeze over a filter very
easily, making for a very cold walk home. This was standard
procedure on the big truck, as diesel is often contaminated; I
finally started using filters with drain plugs, which I checked
regularly for water.)<br>

I once spent a winter evening in my MGB-GT with the battery
cover off of the car so I could tap the fuel pump with the lug
wrench every 10 miles for 130 miles to keep enough fuel flowing
to get me home. SU Fuel pumps don't really die, they become
zombies that need to be resurrected.<br>
I had a similar problem to yours that turned out to be worn
needles and seats in the carbs. The seats were worn to a point
that the needles would stick. Sometimes the rattle from the
last gasp of the engine would shake them loose, other times a
quick rap from the handle end of a screwdriver would shake them
loose. Real Grose jets cured the issue.<br>

times I have driven the car it does the same thing. It
will be running just fine and then it will start to act
as if it is running out of gas. Stumbling and trying to
die.... After I bleep the throttle a few times thinking
it is truly "AAA time" the car will run just fine. There
is a fuel filter between the gas tank and fuel pump. The
filter doesn't look freshly installed, however, it is
not needing replacement. The fuel pump is an electronic
unit not SU. Should I suspect the fuel pump? In the past
when I needed to replace a pump it was dead --- not
working part of the time and fine later. What should I
check first??? Arch<br>
