I have a 98 honda civic. This morning on my way to work, while waiting at a traffic light, engine just turned off by itself. I couldn't restart it right after; had to push it to the curb. But only after a few minutes, I could start it, then I drove to work (trip from home to work is only 5 miles) Now I recall something unusual happened earlier when I was driving, RPM suddenly went up and then dropped right away, while my foot was as usual on the gas pedal.
What could be the problem? Do I need to take it to the mechanics ASAP?
First thing you need to do is have the comouter scanned for codes. Post the exact code numbers not code descriptions.

You should get it checked asap but then again this being an intermittent problem you might not find anything. If there are no trouble codes, it is going to be a problem tracking the cause unless the problem resurfaces again.
There are many possibilities for it to occur and it could be ignition switch, fuel pump, its relay or engine control.

Hi, saturntech9, thanks for your reply. But the engine light is not on. I went to autozone, and they wouldn't scan my car.
The problem has become more often. RPM just dropped to zero while driving (2 times in a short trip), but if I keep pushing the gas pedal, it would come up again.
If it is like KHLow2008 said, it could be difficult to track the cause, where should I start first?
Thanks for all your kind help!

Thats why I suggested having the codes read with the light on or not that would be your best bet to maybe get a lead as to what is going on.

Start with the PGM-FI main relay, ignition switch.
