I suppose 5.15V on U7 pin 3 is typo (pin 1 and 3 are connected together), otherwise everything looks as should.

0.4A at 5.15V is perfectly normal, so the problem might be that digitizer and FPGA bottom ground/thermal pads are not soldered properly on PCB. If that is the case, heat transfer from those chips is bad which can create hotspots and eventually cause instability when their temperature rises high enough. The way to fix that would be reflowing/resoldering the ground pads on the bottom of the ICs, but if you’ve bought from VGP, you should just RMA the board.
