If this has been addressed before, I'm sorry,
I have a 2005 3/4 ton silerado that has been dying on me going down the road. Most of the time I can kick it up into neutral while still rolling,and start it right back up. One time (after I towed it home) It took about 3 hours for it to start again. This last time,it died and 2 1/2 hours later still wouldn't start (stranded me and my 2 boys, and ruined a fishing trip) I have about decided it is the crankshaft position sensor, and have one ordered, WHERE is it, and how hard is it to change? I have been searching the internet for 3 hours, and haven't found any usefull information, this site looks like my best bet!

am I on the right track here or what?

the sensor is no problem to change,(for anyone else that wants to know) 2 starter bolts, drop the starter, 1 bolt for the sensor, 10 minutes max. Problem is........didn't get home before the dern truck laid down on me again GRRRRRRR!

what made you decide its the crank sensor?I work at a chevy dealer and have for 18 years and have yet to see a crank sensor go bad in a v 8 like you have.it needs to be diagnosed by someone who knows what theyre doing or your gonna spend lots and probably never fix it.imo I would check for a fuel related concern as the ignition systems on those engines are pretty much bulletproof,not saying it cant happen but isnt likely.

Is this a small block or big block truck?I have also never seen a crank sensor go bad on a newer 4.8,5.3,or 6.0 liter engine.The big block engines do have some issues though.
