Engine died, then weird stuff with idling

[hai1206vn]

Ok, so I was pushing the car for a while and suddenly the engine died at about 6000rpm. Of course braking and steering got heavier. I restarted the engine while the car was still rolling, and it turned back on but the rev fluctuates rapidly between 300-700rpm, then died again.

I brought the car to a complete stop and tried to restart. Same idling problem happened again, and it died. Coolant temperature was still in normal range, and I couldn't find anything that burned in the engine bay. 3 minutes later I retried and things were back to normal

Did anyone experience this? I can only think of 2 possible reasons: (1) either there's some kind of thermostat that regulates the temperature, or (2) the throttle cable was stretched for a long time and got some slack, so couldn't hold the idle rev constant.

Thanks in advance for your input, guys.

The same thing happened in my Dad's 79 Trans Am. Only everything started working normal after sitting dead for 2 weeks. It could be that your computer was getting some bad readings and shut things down. I really dunno what the cause could be....Let us know if it happens again and more about the circumstances.

I think I've found a similar case, which says that the reason is the speed or rev limiterhttp://www.240sx.org/faq/articles/spdgov.htm(look at the "Rev Limiter" section by Chano, 2nd from bottom)

Did you test the MAF or fuel system?

Check your ECU for codes.
