[Shotimes] Cutting out???

[Donald Mallinson]

I agree that the DIS can sometimes act like that, but another thing to 
check is the connorctor/bundle of wires that goes into the coil pack.  
This can sometimes work loose, or be damaged or not put back in 
correctly when worked on.  It can cause an  intermittent failure of the 
ignition.    Seen it happen more than a couple times.
