Why does the engine stop?

I have a car (mazda) whose engine started misbehaving about six months ago by going off once in a while but more often in the recent past. This usually happens on hilly areas, rough roads or in traffic jams ( slow speed). No firm diagnosis has been made though many solutions have been tried or suggested. Anyone who can help? I care!

Engine just stops. Wah! In the business world, everyone is paid in two coins - cash and experience. Take the experience first; the cash will come later - H Geneen

@thuks,
Does the car start up ok in the morning i.e no hard start?Is the idling speed ok just before it goes off?Does the CEL light up?Does it start ok(after going off)?Where was the diagnosis done,CMC?From my experience a scanner For mazda vehicles differs from one used for the other Jap cars i.e a scanner that is used to scan a toyota cannot be used to scan a mazda...I could be wrong

Anyone who can help? I have the same problem with Toyota NZE my mechanic changed a sensor cant recall the name ( ile inaleta moto kwa plugs as he put it and it seems to be ok. when i had that problem i used to have a hard start if the engine stops and early in the mornings, i am however giving its sometime before am sure. since even previously it would function ok for a period that start misbehaving.

Those computer diagnosis dont work!
