The poured concrete foundation in my 30 yr old home has horizontal cracks in many places, about 4 inches from top of stemwall. In fact, the top section is for all intents and purposes separated from the lower stemwall in these areas. Should I have this fixed by injecting epoxy in the crack, or by breaking out and repouring the damaged concrete?

Leon,
Continuous horizontal cracks in poured concrete are most-likely indicative of a "cold-joint." This four inches wasprobably poured at a different time than the remainder of the wall, and thus it did not bond properly. Many years of expansion and contraction may have resulted in the additional cracking.
I'd advise that you call in a structural engineer or a licensed architect to assess your situation and propose any remedial action. Leave the repairs to qualified builder, who has the experience and equipment to do the job properly and safely.
Andrew.
