I made several ferry flights this morning and experienced a total GPS outage while circumnavigating south of the MSP Class B airspace. Specifically; I was flying the 2;300 feet corridor. While in the vicinity of the MN Zoo and Lake Alimagnet; 7 nm off of FGT; I experienced a total GPS outage on all flights. The aircraft were equipped with Garmin GTN 750 avionics experienced the failure. One aircraft had a Garmin 530 WAAS and did not lose the GPS signal; but did experience a brief MSG annunciation that lasted just a few seconds.
Small aircraft pilot reported GPS outages and issues flying between FCM and SGS  airports during multiple flights involving different aircraft types and GPS systems.
