Narrative:

Departed 1.5 hours after scheduled; due to delays associated with winter operations and ATC traffic flow. On climb out; passing 15;000 feet; field configuration light illuminates; in conjunction with a 2;200 lb fuel imbalance. The same scenario occurred on the previous leg; around the same altitude.in compliance with the QRH; turned on cross feed pumps to balance the fuel. Immediately upon configuring the aircraft for cross feed; the master warning light and associated EICAS notifications illuminate. Over the next 20 minutes; the EICAS messages and warning lights illuminate intermittently; and the fuel quantity gauges sequentially fail. The left quantity gauge indicates a fuel loss of nearly 14;000 lbs (16;000 to 2;200 lbs); fails; and then resumes indicating with inaccurate quantities. The totalizer also fails or reports inaccurate quantities.we accomplish the QRH procedure for a suspected 'fuel leak' which directs us to not accomplish the cross feed procedure. We also coordinate with the flight attendants (flight attendant) to visually check to see if they can detect fuel possibly leaking from the wings as contrails. They verify that they do not see any fuel leaking.we immediately contact dispatch and maintenance via satcom to discuss the situation and possible resolutions. We indicate that we're fairly certain that it is probably an indicator problem. However considering the the operational and weather situations in newark; we are uncomfortable taking a plane with known malfunctions into a degraded airport; when we have viable stations to divert to with adequate support. After coordinating with dispatch; maintenance control and the duty manager; we concur that we will divert into ZZZ.we execute the divert in accordance with flight manual procedures; and land without incident.
