2004 Hemi Durango - not starting

I have a 2004 hemi ltd durango 25k on the odometer. 10 days ago vehicle would not start, turn the key would get a single crank, after three tries no crank. Finally starts, take to dealer and again wont start..no codes present dealer returns veh to me. That day pick it up, drive 4 miles down road, turn off, come back to veh wont start. Finally starts take back to dealer and wont re start. Dealer keeps for 4 days still no codes and again returns veh to me.

My question is, anyone else out there dealing with such an issue ? and if so....what has been done to correct the problem ? I am losing patience with well paid service techs telling me there will be no repair until the veh spits out a code. Does anyone have the ability these days to correctly repair a car without the direction of the almighty computer ?????

Thank you all for your time and thanks in advance for any help or suggestions you may have ...

Don't know if this will help or not, but my 03 GMC Truck did the same thing. Had to do with the security system, no codes, no nothing, just wouldn't start sometimes. Sometimes it would run for about 15 seconds and then die. No codes, but GM knew about the problem. Ordered a new "brain" for it and all has been well ever since.

Thank you for such a quick reply. Taking the D to a different dealer on monday, will ask them to look into the security system as a possible culprit.
