It definitely sounds like you have an intermittent electrical connection.
Have you checked the ground connection as well?

The problem may not be in the plug/pins maybe there is a solder joint that
broke loose on a connector or turret somewhere in the cable or under the
deck. It's interesting how we overlook the connectors in the wiring
harness; you may need to open up the connector shell and check those
bifurcated cups (that is what they are called).

You need a really brightly lit work area with a magnifying viewer (one of
those big magnifying lights with the circular fluorescent bulbs is ideal) a
hot, very small tipped soldering iron and a few inches of fine solder.

Look at every connection near and associated with the plug/socket. There
may be one that has cracked and is now motion/vibration/position sensitive.
Sometimes it is really hard to tell just by looking, you want a smooth
shiny connection from object to object. Frequently I will go through and
just touch/reheat/reflow the solder joints until they are all freshly shiny
and the oxidation is gone. It is amazing at how in going through that
process when looking through a magnifying lens will really help you focus
on what you are seeing in the deck. (it is a bit like Zen).

If you do not have fine motor control and a light touch with a soldering
iron (I am an artist with hot metallic objects (a.k.a branding irons), just
ask my ex boyfriend <joke>) then you might want someone else to do this for
you. Do not go horsing around components as you will break things or burn
insulation off of wires.

Ok, enough mental distractions; back to staring at the side of the Willis
(Sears) tower across the street. I am in downtown Chicago this weekend.
