Starts, then Dies V70-XC70 1999

Last fall, the engine would roar to life only to die a second or so later. Start it again, and it would again fail to continue running. I cleaned off and applied dielectric grease to the AMM connections, and replaced the battery and the problem went away.
Today, it came back. I disconnected the AMM this time (knowing a little more) and the same symptoms occurred when I attempted to start the car.
If anyone has any suggestions as to how to approach diagnosing this, I'd appreciate it. Thanks

Marty Wolfson

    Try another key. I had exactly the same problem and it was due to a defective key. There is a microchip inside the plastic part of the key.
    There is a known issue with the connector to the antenna ring (the "AMM"?), I believe the crimp terminals was not done properly. It will give the same symptom
