Losing power when accelerating on 2nd and upper gears around 1500 to 2000 RPMs

Hey folks,
I have a 2004 Matrix and I'm losing power when accelerating on 2nd and upper gears around 1500 to 2000 RPMs.
The car starts to shake and doesn't accelerate as well as before.
It goes away after around 20 minutes of driving but, it's getting worse - I probably should stop until I sort that out.
Do you know what should I do?
I was thinking on the spark plugs, but not sure.
More info: I'm from Winnipeg, and the problem started when it was -10 C outside - probably not related as I never had this problem even with -30 C outside.

But the list of possibilities is very long here, ranging from tune up issues like spark plugs and cables (suggesting you have a misfire) to such things as a clogging catalytic converter to fuel delivery issues (clogged fuel filter, defective fuel pressure regulator, defective fuel pump).
Without the right diagnostic tools in place, you'd be working in the dark. You could have the car scanned for trouble codes (not all problems light the CEL, and not all problems store a code, however). but very often with these types of "intermittent" problems you have to have things like a spark tester and fuel pressure tester on hand for when the problem is actually happening.
Update:
I got my car scanned and showed that cylinder 1 has a misfire.
As well as a known catalytic converter not fully operative (previous mechanic told me not to worry about it).
I'll give one more update by the end of the day as I'm going to take it for a detailed check.
The problem seems to be on lower RPMs as when I extend the gear a little bit more, I don't have the issue.
The problem was caused by an old spark plug.
The mechanic also found some water on the surroundings so, they also replaced the valve cover gasket set.
Problem solved!
