I'll bet the in-tank sock fuel filter is clogged. Happened to my BJ8 once and took me a few years to figure it out.

I have had 2 electric fuel pumps in parallel on my BT7 for years. One went about 3 months ago. I just thought it was old age. Since then the car has become fuel starved on 2 occasions. It sills run for a short distance and then dies, full choke sometimes keeps it sputtering along for a while. Both pumps are working (they click very fast) but no fuel delivery to the carbs when it begins to die (scant fuel and a occasional bubble in the filter). On each of 3 occasions one of the pumps eventually died while the other kept going but still no fuel (shut it off so I didn't have to replace 2 pumps). The dead pump wouldn't work at first on the bench but after shooting some lubricant into it it began to run-seemed like the impeller had become stuck. After being towed home the car started right up the next

I think the pumps are not getting gas which I suspect lubricates the impeller then it binds and the pump stops. Gas tank seems ok, no leaks. no junk and the filter before the carbs is clean. Any ideas.
