1999 chevy s10 starts but won't stay running.

I have a 1999 chevy s10 2.2 L that just shut down while driving , I have replaced crank shaft sensor, ecm, ignition control module , coil packs and still having issues, she will start now but won't stay running, any ideas what else it could be, please help it has been down for almost 5 months.

Does the "Security" light in the instrument cluster come or blink when it stalls?
