this is quite common. i found that cleaning the MAF (Mass Air Flow meter) completely cured this... until it happened again. ;)

ultimately the MAF had to be replaced.

you can test this by removing the MAF, then disconnecting the battery for a minute (have radio code handy if your radio needs one), the reconnect the battery (this will reset the DME/ECU) and see if you get the same hesitation with the MAF removed.

the hesitation is usually right around the 5K RPM mark. for me, it was like the engine just completely cut out for a second once i approached 5K RPMs.

give it a shot of MAF cleaner/electrical contact cleaner. see if it clears up.
