I doubt the trainer is the issue. It sounds as if you've got a leak in your tube.
Perhaps you don't have enough air in your tire, and are pinching it when you compress the tire into the trainer? I'd change the tube, pump your tire up to the normal range (on sidewall of tire), and make sure your tire is not getting too much compression when in the trainer.
