I have seen a bad ground to the data connector cause this issue, the scanner acts as the ground and when you remove it the PCM shuts down. Here is a guide to help you test the ground and the wiring for the data connector which I have marked so you can see which terminals to test.

Connect the test light to power to test the grounds. Check out the images (below). Please upload pictures or videos in your response of any problems so we can see what to help you with.
