On the 1999 - 2000 5.7 vortec engines the distributor gears wear causing the timing to change 2 or more degrees. The ecm is designed to shut down at 2 or more degreedifference. This is in a GM bulletin that recommends replacement at 160k miles. Mine went out at 150k miles. Very similar driving symtoms until it quit running. Both cam sensor codes were set on mine though, not the crank sensor.

Hello. One way to check if it is working is when you try to start the car does the needle move on you tac? If not then your crank sensor is more then likely the problem. It is located on the backside of the engine under the intake manifold. If is in about the center of the block. There will be a 10mm bolt holding the sensor in. If you decide to change it yourself (not to terrible of a job) unplug the sensor, remove the bolt and spin it back and forth slightly while pulling it out. It may be stoburn and you might have to work at it for a little bit (not a done of room) but it will come. When it's out the sensor will be shaped kind of like an L. I have changed a few of these over time and they can be a little stoburn. To install just reverse the process.

The crank sensor is on the front of your engine behind the harmonic balancer. You will need a balancer puller for a 3.8 and a crank sensor alignment tool to do this lob.
