It sounds like the socket is opening up. The legal option is replace cord.
The old fashioned answer is to cut the end off, and put a new socket on.
In between answer might be to buy a short cord, plug that into your 75. And
then use the short cord from the 75 to the appliance. Replace short cord
when it loosens up.

My electric cord falls off of lawn mower. It always did this once in a
while but it's gotten much worse. It also falls off of my weed
Any helpful suggestions?
In both cases, I use the provided gizmo to hold the cord, and they
work, but the 6 inches of cord or more between the gizmo and 2
electric prongs is enough to make the cord fall out or off.
I'm using a 75' orange electric cord with one 3-prong receptacle on
the end. The mower and weed wacker are both Black and Decker, ten or
more years old.
The prongs in each case are one layer of metal, so I can't open them
like with two-layer prongs. With other things, I would bend one
prong away from the other, and that usually worked, but it hasn't
here. If I bend too far apart, I can't plug the thing in at all.
OTOH, I"ve never had success bending prongs closer to each other.
With the lawn mower, its prongs face alsmost down, so gravity alone
does most of the pulling on the cord. It used to last 10 minutes or
more, but now it's often as short as a minute or two until it falls
out. . The end of the cord is warmer than it should be.
With the weedwacker, the prongs are horizontal, the gizmo into which
a loop of the cord is inserted is right below the prongs, and every 10
minutes or so, the cord works far enough away from all the way in that
it doesn't make contact electrically.
