[TR] Electrical Gremlin

[Greg Lemon]

To focus on what Randall said "float bowls have no fuel in them" Car won't
run without it, do you have a clogged line?  I have had this happen on
several cars, fuel flows when you turn the car on, whatever is restricting
(usually chunks or tiny flakes of rust) is drawn to they line intake on the
tank or other point of restriction and fuel stops, sometimes runs for a few
minutes, sometimes ten or 15.  You stop for long enough it will start again
and repeat the cycle.

Just a thought.
