Brand-new Q shuts down after a couple of minutes, must turn back on, and over and ove I received a new Motorola Q today from Verizon as a replacement for my previous one (which after several months of use shut off and simply would not power back on). The new unit has a similar but slightly different problem: after being on for a couple of minutes, it shuts off. (It will restart though, but then shut off after a copule of minutes.) Has anyone seen this problem? Is there any solution? Thanks!
