I'm not sure if this is at all related to your issue, but I have had the same issue taking off from KSJC. After ~30-60 seconds, I get a ~10 second pause. This has happened with every version of P3D v4 since v4.0 to v4.5.14.34698 and before I ever installed Orbx KSJC. No change after installing KSJC. This appears to be an issue with Prepar3D, but I have never completely researched a solution. If you find a solution to your issue, maybe it will fix mine.
