This resolves after a full power cycle. GPS chip related?

Indicator that something else is up with either the GPS chip or the driver. Needs more exploration.

Test Plan: Test 5, 10, 15, and 20 minute sessions on v2.0.0.4 on SN0005. Repeat test on SN0003 if GPS works.

This appears to be not fixable without a rewrite of the GPS module. Marking as duplicate of #1
