Check your fuel filter... just barely enough petrol may be getting by to let
it run.
Another problem I have ran into w/ same symptoms:
A long time ago my idiot ex-husband decided to "steal" some gas outta my
tank. In doing so he left chunks of the fuel hose in the tank. It had
shredded when he pulled it out of the filler neck. I kept changing the
filters as they quickly filled up w/ gunk. Years later, this same problem
re-occurred. I took the mechanical fuel pump apart ( The top easily unscrews-
thank goodness you can do this !) and picked out tons of crud. Buckled it
back up, and it's ran like a champ ever since.
SU float bowl tops are fortunately easy to pop off & insepect for foreign
objects too.
Another interesting fuel anecdote: Back in my "British days" I inherited a
Cortina that somone had given up hope on. There was evidence of a new fuel
pump/filters, and a recent carb teardown. Still would just start, then
sputter & die. Turns out that somone had used a shop rag as a temporary gas
cap, and the darned thing fell in the tank. When vaccuum hit the lines, it
sucked the rag up to the pickup. When the engine starved itself out, it would
die, and the rag would fall back, letting enough petrol through to go through
the whole routine again. (Hmmm...I know I'll take crap over this, but BOY do
I miss that car!)
Good Luck !!
