I have a 2000, and it's doing the same thing, and it's driving me nuts. It happened one day when I was sitting at a stop, and I slammed my foot on the gas and it stalled, and now it does the same thing you're talking about. Did you figure it out? If so, could you email me what you did? wii_modding@live.com

Check your catalytic converter.

So it was none of the sensors. I can think of some things that could be at fault.
1. The throttle body and EGR system need cleaning.
2. The charger is not working correctly.
3. The fuel pressure is not up to snug (pump, regulator).
4. The engine is coked up with carbon deposits.
I would give it a "Seafoam" treatment first. Only because it is cheap and effective on deposits. I also would try higher octane fuel.
Did you check with Mazda Forums?
