2000 Chevy Blazer 6 cyl Four Wheel Drive Automatic

2000 Chevy blazer is hard to start and will not stay running with the MAF sensor plugged in. If I un plug the MAF it will start and stay running. I can plug the sensor back in while it is running and it will stay running until I shut it off. Replaced fuel filter, checked all injectors, replaced fuel pressure regulator, checked fuel pressure at rail (60-63 drops 5 when running) swapped O2 sensors, replaced IAC, no DTC's, replaced MAF sensor.
