Recheck this with the CPU and memory at default levels. 

Have you tried turning off the osd and running battlefield in 64bit? I and many others have been experiencing the drop to 0% gpu usage bug for a while but we mostly have 700 series cards. It seems to only effect 780/ti/titan/black cards but could also effect 900 series cards. I remember seeing a thread on the geforce forums running a 980 same thing would happen to him. He said it ended up being his HDD as he saw disk usage drop whenever the GPU usage dropped. Games installed on your tb? Maybe install on your ssd and test?

origin in-game disabled? uninstall afterburner/precisionx? it could be the drivers atm. i've been experiencing the same problem as you for a while with my 2 780 ti's. the only driver that removes the stutter/drop is 331.82 or 331.93 but the driver is over a year old and might not work with your 970 even if you mod the ini file

Any help ?

This is a Driver Issue.

Nice OP very informative about your system. That being said the most I can advice you with would be testing your GPU in another working PC to be certain if it's the culprit.
