1. when i'm driving on the highway at a consistent speed (60 or 70 mph) i notice that all the power is gone. i can put the pedal to the floor and it will not accelerate.

Could be you CAT, but could be fuel system, or ... or...

2. this happened to me twice, when i'm coming down a hill using cruise control the car should apply the brakes or something to keep me at the same speed but instead the car has gotten up to 10mph faster and when it gets up there i think maybe it decides to try to slow down but it doesn't. it just jerks. rpms up then down and up then down and it feels like a bad fuel pump or something.

The cruise will never apply brakes. If the hill is steep enough and your gear is high enough, then you'll pick up speed if the compression of the motor isn't enough to slow it down. This is the same in all cars.

3. also on the highway when i realize that i don't have any power, if i take my foot off the gas (not in gear) the rpms will drop but they don't stop at 1000 (idle) they just keep dropping to zero. the car won't start again for at least five min.

<no idea>
4. i have had a cel (p2096) intermittently.

Read this thread - same issues as you. https://www.rx8club.com/showthread.p...ighlight=p2096
End result: (on page 2) "Well, its confirmed...NEW ENGINE"

5. also my idle isn't always 1000. when its not running right the idle is more like 800 and the car shakes badly. it will also making a loud ticking noise.
6. there is also a noise that sounds like a fan that goes off when the clutch is out but comes back when the clutch is in. i have no idea what that was. i noticed it in a drive thru yesterday.

any ideas?
at first i thought it was emissions now i think maybe electrical but i don't know.
