Narrative:

Loss of GPS signal and primary navigation equipment while in flight. Signal was lost twice and service restored within 10 minutes. Longest duration of outage was 5 minutes. Loss of primary GPS navigation was reported to rfd approach. After discussing this with other local airmen; I believe there may be a source of interference in this area. Another pilot reported loss of GPS while en route at low altitude through this same area.
