Bad wire to fuel pump?

I have a 1999 Dodge Ram, 114,000 miles, 4x4 extended cab,
A few days ago I went out to start it and it would turn over fine, it just wouldn't start. No gas was getting to the engine. I realized that
the fuel pump, which is in the gas tank, was not making that "noise" when I turned the key. This is a fairly new fuel pump, two years old.
I got underneath the truck and wiggled the wires closest to the gas tank.
The truck then started.
Me not being much of a mechanic and not really wanting to take the tank off and check the fuel pump, I brought it to a garage. They couldn't get it to NOT work. They checked all the plugs and connections and could find nothing, but they also didn't take the tank off and check the fuel pump connection.
Of course the problem is, if I could just wiggle that wire to make it work, who's to say another wiggle caused by a bump on the road will make it not work and cause me to get stranded on the side of the road?
Any thoughts?

Likely reason is a bad connector. The pump is getting older and is starting to draw more current. That current going through the connector will cause heat if the connection is also older and corroded. This causes the connection to fail. On many vehicles a standard repair procedure when replacing the fuel pump is to also replace the connector pigtail due to the damage from corrosion/heat.
If it were mine I would get a new pump and connector (many of the pumps come with a pigtail for the above reason) Then I would plan on changing it out. That tank isn't hard to drop and the pump isn't hard to change either.
