Where electrical systems are concerned....cleanliness is more important than godliness!!
If there is any doubt in your mind that the connection is bad....IT IS.
With a problem like yours....the first thing I would do is jump around the plug/socket connection one wire at a time...in other words, make a temporary connection from before the plug to after the plug on each wire in the bundle.
If the actual problem is the connector itself....replace it...or...recrimp the female metal sockets to provide more grip to the male part of the plug (just be careful not to collapse the socket completely).
You can help things along by using a contact cleaner on both sides of the connectors...also..try Stabline 22 or similar to enhance the connections (it's a liquid that helps keep things clean and conductive).
Good luck
