Strange jolts while driving

2005 Maxima 180K-ish miles
I bought this car about 6 months ago. Drove the car on it's first road trip about 5 months ago. After several hrs, at hwy speed the cruise would disengage. It did the same thing on the next road trip about a month later. I can't with any confidence say if the cruise continued to not work or would drop out.
This past week I took another long trip. The cruise dropped out after about 3 hrs driving, but I could re-engage it. At about 250 miles, the cruise dropped out again and I opted for manual (foot) control. Now the more troublesome problem (and probably related) started. The car would "shutter" one time. By shutter I mean that the car would for one "snap of the finger" decelerate with a "jolt-like" bump then continue. These shutters (http://viglink.pgpartner.com/rd.php?r=5316&m=1640853905&q=n&rdgt=1413390843&it=1413822843&et=1413995643&priceret=11.75&pg=~~3&k=b05e511a1d58d649a688fc2bb0da6fc4&source=feed&url=http%3A%2F%2Fwww%2Eamazon%2Ecom%2Fdp%2FB00MBWO 0F6%2Fref%3Dasc%5Fdf%5FB00MBWO0F63258634%3Fsmid%3D A1Q4A7YXTO45KY%26tag%3Dpgmp%2D1585%2D01%2D20%26lin kCode%3Ddf0%26creative%3D395109%26creativeASIN%3DB 00MBWO0F6&st=feed&mt=~~~~~~~~n~~~) are sporadic. Secs to mins apart. More than not, 5-10 mins apart. Most times in singles, sometimes in pairs, or less frequently in triplets (only once that I could remember). The triplet was at acceleration from an almost stop, but that was the only time at any speed below 60mph.
The next morning I drove for about 1 hr at hwy speeds (cruise on and off) with no issues.
The next day the trip resumed. The problem repeated at about 250-300 miles (cruise dropped out, then the shutters started).
Each day (with 2 days in between that included only 20 - 30 miles of local driving each day with no issues) the total miles driven was approx. 500 miles.
When the shutters (http://viglink.pgpartner.com/rd.php?r=5316&m=1640853905&q=n&rdgt=1413390843&it=1413822843&et=1413995643&priceret=11.75&pg=~~3&k=b05e511a1d58d649a688fc2bb0da6fc4&source=feed&url=http%3A%2F%2Fwww%2Eamazon%2Ecom%2Fdp%2FB00MBWO 0F6%2Fref%3Dasc%5Fdf%5FB00MBWO0F63258634%3Fsmid%3D A1Q4A7YXTO45KY%26tag%3Dpgmp%2D1585%2D01%2D20%26lin kCode%3Ddf0%26creative%3D395109%26creativeASIN%3DB 00MBWO0F6&st=feed&mt=~~~~~~~~n~~~) occur there is no drop or surge of RPMs on the tach. Transmission? Fuel pump? Heat sounds like the root cause.
Thanks for any ideas,
David
