Stuttering and Out of Sync Playback in Logic Pro X

I'm having a problem with my playback.

About 1 of every 4 times I play back audio, Logic experiences stuttering; portions glitch up and the output cuts in and out.

Then the project plays out of sync for a few seconds before the system recovers.

This is happening on very simple scratch projects with 4 tracks or less, and about once every 4 times I hit play (which is unacceptable in my mind).

It also happens during recording which is very frustrating.

All my drivers are up to date, I've used disk utility to clean my system and repair permissions, and I have a very fast and current computer.

My projects are on my internal drive, and set at 96khz 24-bit; but again, these are very simple tracks running off of a "blazing fast" PCIE solid-state drive.

I'm beginning to think this is a hardware problem, as I experience pops and clicks when I first play any audio on any app after the system has been idle. The cut out effect also occurs with iTunes once in a blue moon.

Thoughts?

MacBook Pro with Retina display, OS X Mavericks (10.9.3), 2.6 Ghz i7, 1TB, 16GB Ram, Nvidia

What is Logic's I/O Buffer set at?

Not sure what you're using for an audio Interface but 96kHz is overkill. Unless you have a pristine listening room, many $$$ worth of monitor speakers and amplifier... the best mics, instruments, yes in can make a difference with soft instruments + a lot of effects but even then. I hope you have a high end audio interface otherwise it's pointless and unnecessarily hard on your system. Also, recent versions of OSX do a lot of writing to the drive. What make is the solid state drive, there is a known issue with some recent Samsung drives.

Logic does better running loops/recording/playback from a separate drive although it normally should be able to handle a few tracks. Are you running any applications in the background? If so close them.
