My 2002 GMC Yukon does this also. I will be driving down the road and it just shuts off. Sometimes it will crank but won't stay running, it acts like it is not getting gas. I have had the fuel filter changed the fuel pump changed, 02 sensor and other things and none of it has helped. My light does not come on in the dash and mechanics have ran diagnostics and it gives them this weird response for the 02 sensor. What I have discovered is that this happens when it is hot outside and the air is running pretty good and it does not have to be for long.
