Not unless the sites have been hacked, gone down, or been changed to something not good. Having a godd recource page won't cause a penality unless the link leads to a bad page, malyware etc.
You got something else going on and with the limited information no way to give any helpful advice other than what I already said. I would revisit all the links out and make sure the information hasn't changed from a resource to a big problem. If they are still all good you need to see if it isn't your site the problem sounds like it might be to me.
