Narrative:

I tried to crank for my flight to ZZZ. The battery was low so I turned everything off and used only the master switch to crank it and the plane started. I checked the alternator and it was charging properly at 35 amps (which I was told was okay to fly). I left to go to ZZZ with 84 gallons of fuel. My outbound flight was uneventful. I decided not to stop so I performed a touch and go at ZZZ and started my return home. During my return; I experienced flickering of the avionics system several times. At one point I lost power to the screen for about 10 minutes and then it suddenly recovered. I did check the alternator the entire flight and at this time the alternator was functioning appropriately.upon my arrival I decided to do a few touch and goes. I was instructed by the tower to use a right pattern for landing. I did about 6 or 7 of these. On my last touch and go at; after taking off I lost power again to the avionics screen. I was at approximately 100 feet when I experienced significant loss of engine power. The engine never stopped running but the loss of engine noise was prominent in my headset with a change in rpms. I notified the tower; but heard no reply. I could feel the airplane start to sink immediately. I pushed the yoke forward and touched down past the beginning of the runway. The plane then rolled about 75 yards into the wet and muddy terrain. The landing was uneventful. I had no injuries and upon my inspection; there appeared to be no damages to the airplane. I am not sure what the cause of the significant decrease in power was. In my notes; fuel tanks were switched appropriately. The loss of avionics power to the screen was nothing new. It happened to other pilots. The plane was taken for inspection and the mechanics could not find any reason for this to happen.
