Could be a couple of things, Hans.

Could be weak on pick-up i.e. not enough damping hence enrichment when the
throttle is opened, easy to check by pulling out the choke when the
hesitation is happening and seeing if you suddenly roar off into the
winter's gloom.

Could also be a fractured wire inside the dizzie, being disturbed when the
points-plate twists under vacuum change.  Can be verified by removing and
plugging the vacuum line.

A Scimitar GTE I had nearly gave me heart-failure several times by cutting
out or severe hesitation just as I pulled out of a side-road onto a main
road.  In that case the ground connection to the points plate was simply by
sliding contacts rather than a flexible wire, and these contacts were known
to get iffy over time.  The cuire was to install a flexible wire inside the
dizzy, and that completely cleared the problem.  The MGB has that wire
anyway, but it can fracture, as can the points wire.
