Just a stab in the dark, perhaps the centrifugal advance or vacuum advance on the distributor is dirty/damaged and gets stuck when you had been driving with a wide open throttle? Perhaps the distributor vacuum hose collapses under high vacuum and takes a while to recover?

Being an "E" (D-Jet FI), the manifold pressure sensor usually fails with a leaking diaphragm and perhaps yours have an intermittent leak which develops when suddenly closing the throttle. Or the throttle position sensor is dirty and gets stuck when wide open for a while.

Sometimes you get funny faults, for a while my car would suddenly stutter and die after starting in the morning, then start up fine after a minute or two and be fine all day 'till the next day. That turned out to be the distributor cap centre electrode that was broken off and in the morning the car would die when condensation created a leakage path for the high voltage, disappearing with a few minutes heat soak.
