Re: High ISO NR is the culprit, not HTP.

p. 124 of the instruction manual. Resetting to factory defaults enables High ISO NR. Turn it off to restore maximum burst capability.

Highlight Tone Priority on/off has no effect on burst rate.

Edit:
p. 323 gives other causes of lower burst rate:

setting ISO to 12800 or H

Chromatic Aberration correction: Enabled

WB Bracketing enabled

Lemming and Jon, you guys got it. High ISO noise reduction. At gymnastics the other day I was shooting at ISO 1600 and I turned the NR to high to test out the results. I forgot to turn it off because I don't usually shoot at high ISOs.

After I reset the camera to defaults last night the NR was set to standard but I was still having the problem. Why? Because I was in my low-light office and was shooting at ISO 12800 to get a decent shutter speed!

Phew! Thank you!

Lens aberration correction also caused my jpegs bursts to stop at 2 or 3,  Raw I can get up to 7 shots.  Now jpegs on large can go all day...
