Recently when i'm driving around in my prelude, it will just shut off... After i pull over i attempt to start it, it starts runs for split second and then I watch the rpms fall very rapidly to zero.

Not really sure, but was thinking it might be fuel related?

 

check your main relay. usually the problem that ive seen.

 

Ignitor can also cause this.

 

I had this same problem. Turned my car alarm went haywire. But for you I'd say check the main relay, and the ignitor. How long do you have to wait to start your car again b4 it doesn't cut right off?

 

my car did the same thing and it ended up being the o2 sensor.

damn it seems everyone is having probs like this.

 

this happened to my 1st prelude. If its a 97+ it most likely might be your ignition switch. look up the recalls for the 97+ ludes. Honda will fix it for free.

I second the ignition switch. Had it og bad on a 91accord and also a friends 95tl.

 

I will be calling to see if my switch was replaced after the recall... thanks for the replies guys

 

yea its more than likely your ignition switch, because they changed mine for free...while they were changing my o2 sensor, i went to pay and they were like its on us.
