130k miles mostly stock. Edge juice. Truck has plenty of power while running. Has been randomly shutting off like key was turned off. Side of road it cranks no start. Seems like cranking is shaky as if timing would be off. No codes. After several minutes will start. When it finally does the cranking sounds faster and not clunky. Thinking either crank or cam sensor? Sometimes it will go a block before shut off. Other times 80 miles. Happened 5 times today while in the city. I understand both sensors rarely go bad. Possibly chaffed pig tail at one of those sensors? Spent hours reading thru all the forums and found nothing just like this. Looks like there's a sensor on passenger side of block behind pulley. Would that be crank sensor? Thank you for ANY help!!

 

Try unplugging the Edge tuner before doing anything. I know a few people having issues with Edge products right now. After that, check wiring.
