Slight 'shudder' on initial acceleration

Just came back from about a 150 mile ride and about half-way thru noticed an ever so slight shudder / stutter when I'm starting to accelerate. It's just a second or two and then it revs freely and smoothly. This stutter only occurs under load and and revs perfectly all the way up to redline. It's an '05 with 11k miles and has always run perfectly. I'm not a wrench by any means, just adept enough to change oil. Would Seafoam do the trick or is there something more going on?
Thanks
