It's possibly drawing some air but not enough to let the pump work properly for any duration. This would be most likely if you have the stock fuel pump fitted.
Like I said, this is a long shot, but it's not unknown to be the source of similar problems, and is easy enough to check & rule out before you start chasing your tail 
.
Some of the later cars with EEC systems can also cause problems with venting (carb & fuel tank), but your early car shouldn't have any of that gear.

: I'll check it thanks. 2 thoughts make me
: think it may be something else. 1- it

: The car restarts if I am in a coasting
: stall on the highway and restart, the
: power is fine for the next duration of

: Is there a way for the vacuum to
