Default Electrical problems with Suburban

Hi, I own a 2005 Suburban and been having problems with the battery going dead intermittently. Had a tech diagnose batt and alt and both were normal. All dome lights are off and nothing plugged into accessory. Tech checked for constant draw and nothing. Any suggestions?

Check and clean all the battery cables, power and ground. Battery okay, alternator okay, no constant draws. Very odd. Does it go dead every time you leave it overnight? If so, pull a couple of different fuses each night until you find it holds a charge. Then pull one fuse at a time from the last group until you isolate the problem circuit.
