05 Silverado 2500 4wd 6.0 no spark

No spark but then it will start and drive but shuts down randomly, no related codes, no crank or cam signal showing on the scanner when it happens. I just started the diagnosis and ran out of time. Any ideas on possible causes to save me some time?

utube shows broken ground wire behind ps pump. guess I will start there. Happy Thanksgiving Doug and everyone else! Going into food coma! Glad it's not my truck so I can walk away if need be

Update, The U tube video was right. Easy fix that would have taken hours to diagnose.
