Random No Controller In Port 1

[Neipas02]

Hey ladies and gents..

Recently during play I've been getting "No controller in control port one, Please connect controller and press start to continue." Messages from time to time.

Controller isn't the problem (Get the error with both of my controllers)
I'm not sure on the actual controller port though.. It may be to blame.
Connection is good.. Nice and snug.
A second or two after the message shows up i'll hit start and play will resume fine.
It's a V7 fitted with a Matrix Infinity, a flux capacitor, NOS, a super charger, 22 inch rims.. all that junk.
(Game i've been playing is Mercenaries POD)
Anyone have any thoughts? (reguarding a solution and not naked women <-TD & AX this means you fellas)

Appreciate any input.
