You might be progressing too quickly. You want to milk each sector for as long as possible so that you get more scrap and other stuff while things are still easy, before the difficulty goes up in the next sector. Of course the chasing fleet will cap your advancement on resources (but not score if you can beat them flawlessly, as T-hawk demonstrated), but you should keep jumping around the sector until then.
