CGT keeps dying, help!

Hey All

Yesterday my ' 83 CGT started having problems.  I was driving down the 
freeway and it just shut itself off. no sputtering, coughing or anything, it 
was like I just turned off the key except I didn't.   I couldn't restart it 
using the clutch drop method either, I had to turn off the ignition and then 
restart with the key.   It did this 4 times on my way home from work (about 
30 min.)   All the guages looked fine, good oil psi, temps good, good 
voltage.  I thought maybe the coil was having a problem so I changed in a 
spare one I had and gained about 200 RPM at idle, but I don't know if that 
helped because I didn't get to drive it.  Are there any sensors that will 
cause that on a CIS - K-Jet car?  Could it be a problem with the ignition 
switch itself?  Plugs were new last weekend, rotor, cap, and wires only about 
a year old.  Please help!

TIA
