i have a 97 legacy gt 2.5 AUTO....and when accelerating on the highway in fourth gear i would begin to cruise and after a second or two the rpms drop a bit but the speed stays the same....the rpms drop about 500rpm....anyone know what this is?

Probably the torque converter locking up (which it's supposed to do).

Like Shaman said, its got a torque converter clutch, it improves efficiency, because you are running those 250-500 rpm slower, there great when they work, but i had a ford that had a problem with it, and any speed between 35-55 if you weren't on the throttle or the brakes it would cycle on and off, what a pain.

would it feel like a jerking motion at highway speeds cause sometimes i get that.....but it only does it when i reset the ecu and it does it for about 4 or 5 tanks of gas and then stops...why is that?

Because it takes the TCU/ECU that long to learn your driving habits. The computers learn how you drive and adjust acordingly. Also subarus do shift hard, and if you really listen you can sometimes feel the TC lock up in other gears too.

if you during the learning period floor it randomly to....whatever get yourself out of a jam or something....will it screw up the learning process and make it take longer?

nope thats why it takes over 1000 miles to learn
