On top of the transfer case is a vacuum switch with 3 vacuum lines connected to it. This switch controls when vacuum is applied to the vacuum actuator. This switch can fail partly and allow fluid from the transfer case to be sucked up into the vacuum lines and anything connected to them as well. When you replaced the actuator before, did you notice any oily fluid inside of it?

P1133 - Heated Oxygen Sensor (HO2S) Insufficient Switching Bank 1 Sensor 1
I would have the repair shop see if they either damaged or left disconnected the oxygen sensor for engine cylinder bank one upstream sensor, this sensor would have been disconnected if the oil pan was removed.

i had the same problem with my 96 sonoma, just died anywhere at anytime, even happened to shop mechanics. They checked fuel and spark, there was none. Ended up putting a new computer on it and it has not happened again. The computer was not communicating with anything, just be sure that you get new comp. programmed to your vehicle. Had to send mine out and get done

SOURCE: how to replace fuel filter?
if you can't find one, it might be that either it doesn't have one (as some cars) or it might be located inside of fuel pump assemply (inside fuel tank) but that's a longer story :)
