Sounds like the catalatic converter is either pluging up or starting to fail. Either way if this is the problem it will either start having worse performance or just stop runing entirly.

I had this same problem and it was a faulty fuel injector. Check to see if it is wet around any of your fuel injectors.

I have a 1992 q45 I had the same problem i changed my back cats and it still did the same thing coul it be my front ones to

I have a 1995 Mazda 626, I have a similar problem. It dies right at 15 seconds after I hit the gas and remain at 3500 RPM, and I can hardly get up a hill. I have already changed the fuel pump, the injectors were fine, the O2 sensors were fine, changed the air filter, no clogs in the fuel delivery system (yes changed the fuel filter too), changed the plugs and wires, changed the fuel regulator... the only thing left is the catalytic converter is plugged... it's as if my car has Asthma, so I'm looking at the Throttle position sensor. Will keep you updated.

I have this cutting out problem and i think Ive managed to diagnose mine to a faulty fuel pump as you can sometimes hear it activate but when you don't the car does not start. but anyway this is what i tried. fortunately my sister has same cars as me, maybe some of these will help you diagnose your problem.

- throttle position sensor

- crankshaft sensor.

- camshaft sensor

- fuel pump fuse/relay

- lambda sensor

- Cat could be broken up and blocked exhaust system causing poor flow.
