You don't have problems in what sense? You clearly have problems. If you can't run for an hour, you aren't good at long slow distance running. A 2km run is something that might warm you up, but isn't going to produce a lot of adaptation in your cardio system.
If you are serious about fixing this problem, get a heart rate monitor, and figure out the following:
1. What your resting heart rate is
2. What your heart rate is when you are jogging
3. How long it takes for your heart rate to return to near-resting heart rate after the above run.
4. What your heart rate is at the end of the conditioning rounds that you do
5. How much your heart rate has gone down after a minute
If your resting heart rate is already great, then I agree with the advice that you should focus on anaerobic activity. However, from your description of your running, I'd guess that your cardiac output is poor, and you should fix this first.
