2014 D40 ST maf sensor please help

[SilverYD]

Hey all, my d40 had issues recently with losing power. I scanned the code and it came up that the maf sensor was the fault. I replaced the sensor with a genuine hitachi sensor brand new. Now about 2 weeks later I’m losing power again on my way to work. I turned the car on and off a few times but still no difference then I took a look at the maf sensor and it was already properly plugged in but I unplugged it then plugged it back in and the issue went away. Is it possible that it is a fault in the wiring harness? Or maybe even in the plug that attaches to the sensor. I have an egr delete with a resistor fitted into wire #2 on the maf sensor plug wires. Could that resistor have failed? Any help would be appreciated
