I've gotten a code 12 on my 95 grand Cherokee orvis. I've read that it means the battery or power to the ECM disconnected in the last 50 key cycles. I don't know what that means exactly. Any help?

It means the Engine Control Module knows that it should contain some history and it doesn't, so it throws up a Code 12 error code to let you know. It should go away after it has been driven a week or so. If it doesn't go away, go to your local friendly garage, smile sweetly and ask them if they wouldn't mind clearing the code. It takes about 30 seconds with a card reader and they will do it for you free of charge.

Car looses power, bogs down check engine flashes rapidly. No acceleration, then 15 - 30 seconds later power comes back and check engine light goes solid and stays on for 2 or 3 days.Anyone with idea?

You should read check engine code.
It tells you more than you can guess.
You can buy quality $1000 snap-on OBD scanner or $30 cheap one.
$30 will do good job. (you need to google after car tells you error code because cheap scanner shows only code but not meanings in plain English)

or you can visit local autozone and ask them read code for free.
unless you ask car itself, nobody will be accurate.

Can't find OBD Code meanings for the followinng codes 30, 1721, 521 and 653

It can actually depend on the type of vehicle you drive.

If you Google 'Error code 30 Toyota' (or whatever car you own) you will find them.

Error codes are not the same across different vehicles

I still have a engine light on after resetting it. I changed both sensor after a po30 code. Is there a third sensor?

Code 30 is for a problem with the heater in the O2 sensor bank one sensor one. That is the sensor before the catalytic converter.
The code does not mean you should replace the sensor, it means the sensor is not getting hot as it should. The problem could be in the sensor, or the wiring, or the power source.

What does code p1000 mean on 97 experdition 4x4 5.4 motor

It means the motor hasn't completed it's drive cycle. If you've had work done and the battery was disconnected it sometimes trips the code. If it doesn't go away by itself after about 30 miles or so you might need to get the computer reset at a shop.
