My 2006 Pontiac Montana shuts off at times. No warning. Just shuts off and will not start. Will not spin over. It says starting disabled. Just does this occasionally. Stop... wait 1 minute... and it starts back up and runs fine for another few days.
It will do it running 10 mph or 60 mph. I have removed the steering wheel and performed tap and wiggle test around column, BCM, ignition and other wiring. Could not get it to act up. Thanks for any help.

 

Do you have an OBDII code reader that you could plug to check during these no-start periods?
