Steering problem

When in reverse it would sometimes get hard to steer and the radio would cut off. Yesterday in drive it got hard to steer and the radio kept flickering on and off

Hello .. thanks for the donation .. much appreciated

Before performing individual component or system tests, check the following for possible cause of system malfunction.
Tire Pressure
Mechanical Condition Of Steering
Power Steering Fluid Level
Pump Pressure
Faulty Fuse No. 8, 20 Or 23
Loose Or Corroded Connectors
Damaged Wiring
If problem remains after inspection, connect and operate New Generation Star (NGS) Tester (007-00500) following manufacturer's instructions. Perform data link diagnostics test... let me know

Variable Assist Power Steering (VAPS) control system automatically adjusts power steering fluid pressure to provide light steering effort during low speed driving and firm steering during high speed driving. VAPS system consists of Generic Electronic Module (GEM), an actuator solenoid valve assembly, power steering pump, rack and pinion steering gear, hoses and an in-line fluid filter. See Fig. 1 .
VAPS system controls power steering fluid flow through an actuator valve, mounted on steering gear. See Fig. 7 . System uses a rotary valve in steering gear with 2 separate hydraulic circuits. Primary circuit provides greater power assist than secondary circuit. At low speed, fluid is routed through primary circuit by actuator valve. As speed increases, actuator valve gradually opens, diverting fluid to secondary circuit. GEM module has self-diagnostic capabilities. If a fault is detected, VAPS will revert to full steering assist

I'm having a little different issue. When the car is started, the P/S works great for about 30 seconds then decreases to almost nothing. I had the rack replaced, and was told that it moght be air in the system.
A trip to Ford told me that it was the GEM module. It was losing output after 30 seconds. Would this be more of a GEM issue or a Vehicle Speed Sensor issue? Thanks.
