Yes, I have had the same trouble 4 times in 4,200 miles. cranks real fast with no attempt to start, times out and stops cranking, then I retry to starts and starts instantly. has happened 4 times all after a warm restart after shutting down the restarting between 5 mins and 1 hour. I have aborted the time-out crank period by putting the truck in drive with my foot on the brake. Then it restarts and runs smooth as if nothing was ever wrong?
Have talked to several 3.0 Duramax owners that have also have the same problem, They have brought it back to the dealer and the dealer says no Bulletins yet and hard to diagnosis unless they can get to act up. I agree.
