the other day i was driving along and (i now know) my ignition feed fuse blew shutting off all power to my ignition so when i put the truck in to neutral to restart it (i was rolling at 25mph) it didint work. as i slowed to a stop at around 10mph the truck made a bang bang bang rapid engaging sound as if the transfer case was trying to engage in to 4LO then a sudden thud i went another 50 feet and stopped put the truck in park and it was locked in park and i could not budge it because the ignition did not work. i was in the middle of a street so i could not fix it due to the cop who pulled up behind me and said i could not be in the street so after a 165 dollar tow (AAA said the truck was to Big and to heavy...its only 5500lbs! but apparently the guy could not handle it and the 33/13.5's)

So my question is has any one else heard this noise and when engine is off and rolling in neutral?

thanks
