You would still be ok due to the rage. What makes you think you will be in an anti magic field?

I, at least personally, never viewed temporary stat bonuses (any bonus that does not last at least 24 hours) as helping to qualify for feats.
Since rage only lasts for rounds/day, once you enter the antimagic field, your raging vitality feat would be disabled, since you would no longer have the required con of 15.
Same with your second question, going into rage in the antimagic field, would only grant you a temp bonus to con, and thus not qualify for the feat.
Take a look at the PRD section about ability score bonuses
Permanent Bonuses: Ability bonuses with a duration greater than 1 day actually increase the relevant ability score after 24 hours. Modify all skills and statistics related to that ability. This might cause you to gain skill points, hit points, and other bonuses. These bonuses should be noted separately in case they are removed.
I always counted the feats as "other bonuses". Temp bonuses give you very specific, limited bonuses from each attribute. For example, temp int, does not give you extra skill points.
I believe that the general guidelines are that you can keep feats if your conditions fall below their original prerequisites, but they cease to function until you meet them again. So you could take Raging Vitality, but you would lose it in the antimagic field. If that's not in the RAW, it's how I would houserule it, if there aren't any rules contradicting it. You might just have to ignore enhancement bonuses for the purpose of prerequisites.

That is how it was in 3.5. There is probably a similar statement in PF. I just don't know where it is.
I only ask because antimagic fields are rare. You are more likely to encounter a disease, poison, or curse that drops your constitution score. I do think Mahorfeus is correct though. I forgot pathfinder had the temporary ability bonus rule.
The prerequisite in the opening example is Con 15 to take a feat the provides a +2 Con bonus while raging, and this character has a magic item that provides a +2 enhancement bonus to Con.
How about if the character - after legally taking the feat - later had his Con permanently drained down to a base Con of 10? The magic item bumps this Con up to 12. Raging bumps Con up to 16, so the feat can be used while raging to make it Con 18. But in an anti-magic field, the base Con of 10 would not get the +2 from the magic item, so it only goes up to Con 14 while raging, so he does not have the Con 15 prerequisite while in the anti-magic field. Therefore, the Raging Vitality feat would not work in this instance, correct?
I know that this isn't what the opening poster asked but am just curious to see if I have this other example right.
I think the consensus is this: To take a feat you need to have an ability score of X. Enhancement items count for this if worn for more than 1 day (see permanent enhancements). Once you have the feat it's yours forever (excepting fighter). When your ability score drops below X by any means you no longer qualify to use the feat, and this it's basically a dead feat until you repair your ability score.
In an antimagic field, if your score is still above the required level, kudos- it's still in use. If your ability score drops too low because of ability damage or drain, sucks- you need to get that repaired, because your feat is inactive.
