Sudden loss of power

My 1999 Saturn SL2 all of a sudden loss power as i accelerate and going uphill. The "check engine light" is not on and the motor seems to run normal while idling.

automatic or stick? My auto L-300 (Bruno Magli Mobile) had loss of power well before SES light came on. Do you have a code reader for OBD-2?

Automatic. I replaced the spark plugs and O2 Sensor with no change. I don't have a code reader. Going from 0-40 and going uphill as no power. On a straight way, I can hit 80mph with 3500rpm.

Update!!

The car got its power back on its own. I don't know what happen but its running good for now. All I know is it started when I used the cruise control going uphill. So, I'm not using the cruise for now.
