I have heard that TR5s & early TR6s suffered from this problem
because the fuel tank did not have a baffle & all of the fuel would
slosh away from the outlet when cornering. Not sure when the tank was
modified but it had certainly been done by the time your 1974 TR6 was
produced. Could your car have had an earlier tank fitted at some
point?
Do you notice a change in noise from the pump when this happens (& is
it an original Lucas pump)? I don't think either Lucas or Bosch pumps
like to run dry, & I seem to remember that the Lucas unit uses fuel
to lubricate an internal seal, this can break if fuel is not present
(usually due to vaporization on hot days).
