The issue might involve the fact that you use Push Mail or Autoupdates on certain programs. My issue was that I was pushing my mail automatically for Windows Live which kept a Data Connection almost running all the time. This conflicts with AGPS therefore, GPS stops functioning or simply just doesnt get a lock on any satellites.
Read the thread above for a more indepth analysis and procedure to help you with this GPS problem.
I can confirm that, after this solution, OMJ's ROM is not the problem and he continues to deliver good ROMs. I personally use the Clean Generic. I go to OMJ because, while other are bloating the ROMs, including OMJ, he is also creating Clean ROMs. I look for Clean ROMs because I have my own personal programs that I like to use and update as they get upgraded. Thanks OMJ.
