1997 Chevy s10 4.3 liter Vortec engine with 5 speed manual transmission. The truck just shuts of in any gear or any speed even when idling. It seem to be restarting with no problems. Last May or June we put new fuel injectors, map sensors, fuel pressure regulator, O2 sensors and catalytic converter. This has been a problem for a couple of months now. Thanks for your time.

Replace the Ignition Control Module.

Check to see if you have any codes stored in the computer. The crank position sensor could be starting to cut out.
