When you say everything goes dead are we talking all lights, radio, wipers? If so, main power or ground cables bad or fusible link. If just engine, check coil, ignition module, crank/cam position sensor.
SOUND LIKE FAULTY ALTERNATOR. BUT CHECK ALTERNATOR DRIVE BELT AND FUSE AND WIRE CONNECTIONS FOR LOOSENESS AND DAMAGE. TURN OFF RADIO BEFORE DISCONNECTING BATTERY NEGATIVE CABLE TO KEEP FROM LOCKING OUT RADIO.CHECK ALTERNATOR OUT PUT AT BATTERY SHOULD BE 13.5 TO 14.5 VOLTS. IF NOT ALTERNATOR IS FAULTY.

I just changed out the battery on my wife's Lanos and it reset all the electrical info (to be expected)...which included the radio code---so I know what you're going through. Here is a list of the most common codes used in models during the 1998-2001 model years. This list did the trick for us.
You will need to pull the radio and record the serial number and model number off the radio chassis, take that info and your proof of ownership for the car and the dealer should be able to give you that info for free by using the manufacturer online info service they have.
