Help EVO won't charge while vertical

[ghodzilla5150]

I have a phone holder in my car and used it for the 1st time today (I also have a car charger). Well I put the EVO in the holder (Vertical or Straight Up) and the EVO stopped charging. When I took it out of the holder and laid it flat it started charging again. Has anyone heard of this or seen this happen. Thanks

Honestly it sounds like a short in your cable, or maybe /shudder your charging port. I don't see any other reason for this to be happening.
