Stern Flipper fade is real and I see it more than is reported here. It is evident during league night and during long games.
However if you think it is more than that, then figure out what else is on the circuit. Make sure there isn't anything else like a fridge/freezer, AC or even a Plasma TV. I used to pop a circuit when I turned on the TV, so I used extension cords to other circuits for leagues.
It isn't clear if you have more than 1 machine at a time, but play with the others off or move them to other circuits.
How old is your house and if old, has the wiring been upgraded or just had new outlets installed to look new.
The best advice was above, get a meter and do some 'scientific' tests.
