I'm not sure you've given us enough information, but . . . from what you're saying . . . it sounds like you've got some tight links. Here's an article that will explain how to fix this . . . if this is your problem:

It sounds to me that your chainring is out of round. This will cause the chain to tighten at the high spot. If it is a spidered crank, try loosening the chainring bolts just a little and spinning the cranks to the tightest spot, give the front of the ring a tap with a soft mallet, and continue this process all the way around the crank revolution, then tighten them up again. If it's a one-piece chainring, there's not a lot you can do. Just set your chain tension at the high spot and live with a little slack on the rest.
