check the fuel filter
 
My '96 killed a coil pack with similar symptoms a year ago.

Check your fuel pressure (maybe a pump out, or a clogged filter), and spark (fouled plugs or bad pack)
 
if you change the plugs just make sure you put the platinums back in it since its the vortec. Itll run much better.
Vortec's and copper plugs dont like eachother.
