2001 S10 S10 LS Extended Cab 2.2 w/ 5 Spd. w/ 179,300 miles.

The truck started to stall or quit. Can quit at anytime; at the light or at highway speed. Was thinking fuel pump or ignition.

Replaced most of the ignition components: plugs, wires, coils, ignition module.

Problem remains.

Hooked up the laptop, and though there was no engine light, I got a DCT: P1632

From what I gather the PCM is killing the fuel supply. Anything specific to the S10 that might cause a problem in this area? Things seem to be pointing to ignition switch, but my key doesn't appear to have one of those resistors embedded in it.
