More than likely the circuit board on the ECM has a crank in a solder joint. This was not uncommon back then, especially on PT Cruiser. Clearly this is a different vehicle but it is the same idea. If you want to remove the connector and inspect this individual terminal you can but if this were the issue it would not cause it to shut off. The fact that it shuts off shows that you are losing all power to the ECM which is a sign of a failed ECM or multiple fitment issues with the connector.

More than likely you are going to have to replace the ECM so I included the steps on how to do that as well.
