Engine shuts off regularly. And the garage is not able to track the cause.
Very nice car for its purpose, when you have a small family and dogs.

Probable cause is:
1) Dirty fuel filter.
2) Clogged electric fuel pump.
3) If not the above, then is for sure: The electric conduit for the immobilizer, in the area/door where you open or close it!!!
The cable there, breaks easily.
My Peugeot 406 1.8 -97 used to have this problem as well, the motor just stopped when slowing down in idle, e.g. at red lights. The problem was fixed by renewing the controller of the idle running of the motor. I don't know the exact term for this controller/actuator, it is about 3+1 cm push/pull axis. The cost was around 300 (!) euros for the exchange part and work.
