GPS constantly losing connection

[cleanden]

I recently installed Waze on my Nexus One and noticed the GPS is very flaky.

I consistently see the following, whether I'm driving or stationary:
1. GPS works for 12 seconds
2. GPS says 'No GPS. Showing approximate location' for 17-25 seconds
3. Repeat

I'm driving along a major highway in Denver, CO and never see anything like this when using Google Maps.

Is this a known hardware or software problem?

Thanks

Moving it from SD Card to Main Memory fixed it
