Check the fuel cap!! If the vacuum relief is not working it can impede the fuel flow and cause the engine to shut down or not restart after a stop. Waiting usually gives things a chance to stabalize and the engine will restsrt. When this happens again try loosening the cap and see if the engine will restart.....If it restarts immediately, REPLACE the fuel cap..Do Not leave it loose because this will cause other problems. If it is not the fuel cap the problem may be the filter, the fuel pump, or aome other fuel system malfunction.

Harris, did you find a solution to your problem? I am having the same issue on my 04 denali. Rear doors and tailgate wont lock but the unlock fine. Front door function normally? let me know.

contact monroe the people that make replacement shocks. They may have a solution.

I fixed mine by using fine steel wool to clean the brass contacts located at the right upper door frame on the right door as viewed from the rear of the vechicle.
