If it stays connected with the engine not running but drops out with the engine running then it would suggest there is significant electrical noise interrupting the USB comms.

If you contact [email protected] they can run through some suggestions and if its an early version G4X there may be a hardware mod to improve USB noise rejection. 

I would also suggest trying the slow connection mode (in the configuration menu), you need to disconnect and powercycle the ecu for this change to take effect.  And try both USB and a COM port in the connection settings as sometimes one can be better than the other.
