WLtoys V303 Seeker Quadcopter GPS problems.

[Metal Mike]

Hey guys,... I just recently got the V303 Seeker...It flies great, except it's been having problems finding GPS satalite signal, for no apparent reason. One minute, the GPS is fine, the next time, it can't find it,.. and the weather (cloud cover), hasn't changed a bit.
I'm stumped. Does anyone else have this issue, and do you know what the problem is?...
Thanks...
