Car stalls, mazda finds nothing wrong

[Brandon078]

I tried searching here, but since I know almost nothing about cars I wouldn't recognize what I need if I saw it, so anyone have any ideas...

2006 Mazda 3 hatch, maybe 53000 miles. It's only driven to work and back, 22 miles a day round trip. I keep up with maintenance and not aggressive driver at all.

I was driving one day and all of a sudden the RPMs just dropped and the car started to buck, so I pulled over and turned the engine off. It started up fine and I got to work fine. It happened again on the way home so I took it to the dealership and they said they found nothing wrong and couldn't duplicate the problem.

Few days later it happened again, about 8 times though. The final time all the lights came on not just the check engine and it stalled on me so I rolled it off the road, had it towed to the house and haven't driven it at all. I just started it up and it will idle ok but I don't know what to do.

Anyone experience this? Sorry I don't very much about cars but any suggestions or further questions please let me know. I appreciate it...

Does it happen randomly? B/c I've heard of the Mazda 3 stalling when the brakes are engaged, if that's the case could be a vacuum leak. Have your mechanic check for a broken motor mount too, that could also be the cause.
