Q: My ipod shuffle turns off after exactly 30 seconds of play. Already had a similar problem?

Make sure your headphones are plugged ALL the way in, meaning the white part of the headset is flush with the body of the Shuffle.  If you are 100% certain that they already all the way in, check the headphone jack for any signs of debris or damage that would be preventing a full connection.

Did you see my post above?

Have you tried a different set up earbuds to see if that helps?

What about resetting the Shuffle?

My ipod turns off as well and I have checked the head phones as well as the jack in which the head phone plugs into.  Thgouths?

If the headphones are plugged all the way in and the jack is clear and clean of debris, then it's likely that the headphone jack is faulty or damaged and will need to be serviced/replaced.  Before taking or sending it in for service, it might not to restore the Shuffle in iTunes to factory settings to rule any sort of software issue and try a different set of earbuds/headphones.
