Chevrolet Repair: 2002 Chevy 1500 Silverado 4x4, chevy 1500 silverado, crank sensor

Question
The truck just stopped going down the freeway.  Changed the fuel filter, had the battery and alternator checked, they were good.  It started but will not run for very long, any suggestions?

Answer
Were you able to check for codes?  This is more complicated than to just say check this or it is that.  I would need to diagnose it.  However, you can check crank sensor for dirt or obstruction.  Do the same for the cam sensor.  What about obstruction in the exhaust?  Maybe a clogged CAT.  

I wish I could be more help.
