Engine kills off idle

[toneloc60]

I've got a '91 Plymouth Laser non-turbo. It will idle all day long with no problems. However, if you take it off idle it will die about 5 seconds later.

It cuts the ignition, I'm guessing. The reason I say it cuts ignition is due to the fact that the fuel pump remains running for a couple seconds after the cars shuts off.

It doesn't sputter, or gradually die. It simply cuts off like someone turned the key off.

Has anyone seen a problem like this?

Check the capacitors in the ECU.

Thanks a ton! I'll check it when I get home.

It's finally fixed. It wasn't a problem with the ECU. The distributor was bad. Fun stuff. Thanks for the help though.
