Charging issues..

[Vret]

I recently ditched a generic mini USB car charger I had for a USTStarcom specific one from Verizon. The problem I am having/did have is that it would seem that occasionally when running the GPS my xv6900 won't charge. The phone acts as though it is on external power and I get a flashing amber LED, its the one on the left. I'm using OMJ's custom Verizon ROM.

Anyone else seen this or have any suggestions?
