This has nothing to do with the Catalytic converter ! Plugged catalytic converters don't go away after shutting off the vehicle !
This reduced engine power has to do with the
Throttle Actuator Control (TAC) System
Reduced Engine Power Mode When the ECM detects a condition with the TAC system, the ECM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
?€¢
Acceleration limiting--The ECM will continue to use the accelerator pedal for throttle control; however, the vehicle acceleration is limited.


?€¢
Limited throttle mode--The ECM will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.


?€¢
Throttle default mode--The ECM will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.


?€¢
Forced idle mode--The ECM will perform the following actions:


-
Limit engine speed to idle by positioning the throttle position, or by controlling the fuel and spark if the throttle is turned off.


-
Ignore the accelerator pedal input.


?€¢
Engine shutdown mode--The ECM will disable fuel and de-energize the throttle actuator.

Sounds as though you have a clogged, or nearly clogged, Cat Converter.

SOURCE: cobalt

When you have the display panel say engine power reduced...and car stops. The item that needs checking and replacing is called a ECM- Electronic Control Module, it looks like a miniature sealed laptop that plugs in on the drivers side of the engine. We used to have the car do this all the time, until we replaced that module, I have since put 30 K on the car, and it now runs fine. It did cost a few bucks to fix for sure.

What would cause this problem


Still sounds like 'limb mode' to me, but that should trigger some engine-warning light on the dashboard (and definitely internal error codes). The dashboard-light could be broken ofcourse. Would suggest taking it to a dealer for OBD-diagnostics (i.e. reading the internal error codes), that should be a good start.

Guessing what it could be: (MAF, O2) sensors, injectors, overheating (fan not spinning up when need ?), bad fuel, throttle-body, old fluids / oil, clogged fuel / air filters ...

Engine power reduced displayed


sounds like the camshaft sensor or the crankshaft sensor, either way I think your car is being recalled for a faulty ignition switch which could turn off by itself.

I was driving home tonight and all of sudden I felt something slip in engine and the message engine reduced power came across. The symbol t/c came on also. My check engine light has been on for almost two...


Check the drive belt,and the alternator,most likely if the belt is still on,and it is running on the pulleys ok,then the alternator maybe out,have it checked,with out the alternator working the engine will not perform.

Why does reduce engine power light comes on chevy


That is a hard problem to pin point without knowing what codes the computer has stored. It can be any number or sensors or engine problems.

You can go to most auto parts stores and they will pull the codes for you for free.

My 2007 cobalt won't start-displays ''Engine Power Reduced''...what's wrong with it?


The computer has detected a fault in the emissions system that could damage the engine. It disables the engine so you cannot drive it and damage it. It must go to the shop. This sometimes happens after an aftermarket exhaust system is installed and it was not done properly or if engine modifications were done improperly. This can clog the catalytic converter and cause higher back pressure.
