Do the cooling fans come on? Issues with the fans is common. Check the fan relays, temp sensor, wiring, and I believe there is a fuse as well. Any of those can cause an issue.

Also make sure the system is adequately filled. An air pocket can cause issues.

Do a system flush(pull your thermostsat) and make sure all of the hose clamps are tight when putting it back together. The clamps are a common cause of minor leakage that, left unchecked, lowers the level of the coolant. Properly "burp" the system and you should be good. If the problem then continues, you may have a mechanical issue, ie, cracked head, bad head gasket, etc.
