I've found on my truck that if I turn off the key, wait 10 seconds or so, hit the gas pedal a couple times, pray to God in heaven, then restart, it fires right back up when this happens. Found that if I immediately try to turn it over again after it doesn't start, it takes a couple of runs of the starter to get to work. Not a theory(maybe just divine intervention), just what I've found to work. I haven't noticed any clicking noises when it happens nor any smoke once it fires up.
Darn, that half priced 08' hemi 4x4 is starting to look really nice. Too bad though it has that MDS crap on it.
