Not had that with my Daihatsu (which is essentially a Charade, but from a time when carburetors roamed the earth, and computers were kept in air-conditioned rooms) but I have had something similar with a Mk1 Lada,

Not the same, though, since, although initially apparently random, it gradually emerged that it tended to happen on deceleration, and eventually became predictable enough that I regarded it as a primitive precursor of stop stop-start functionality.

Turned out it was (probably) due to a deterioration in the carbon-core of the Soviet-supplied ignition leads, which would stop conducting under negative G. I replaced these with fancy bright orange silicone rubber sheathed "racing" leads and it stopped doing it. Rather missed it.

The key fob suggestion above sounds similar, though the pendulum effect would probably make it seem more random.
