Sounds like MY current game... except I started with low computer bonus, so maybe it's only 2x computer resource generation. But still, there are three races that have just grown like crazy! 120+ colonies each, etc.

And I had a similar problem to yours early on: I had TWO T&R alliances, and was getting well over half of my resources and research from the trade. Even more important, my own production was not enough to pay my maintenance - so I was in a bit of trouble when the alliances went south. Fortunately, I had a LOT of resource storage built up, so I survived until my new colonies could pick up the resource generation slack (and two remote mining battlestations helped too: net gain of 11kT minerals each per turn!).
