Aircraft
After a routine; start up; run-up; and takeoff from ZZZ; with 4 tandem sky divers aboard; we climbed to 10;000 feet MSL; I announced to Approach as usual 1 minute prior to jump. Everything went normal the jumpers jumped out of the plane and nothing happened until the descent. I was circling ZZZ to keep the jumpers in sight because Approach tells me to notify when jumpers are no factor. When I was around 7;000 feet MSL I noticed an abrupt loss of engine power; specifically the manifold pressure gauge decreased close to 0 inches. The engine kept sputtering for a few seconds almost like it was from fuel starvation; but eventually seemed to turn off as if the mags were off when they were still on both. I immediately started my engine failure in flight memory items checklist for a C-182. I either missed or did the magneto check too fast because the engine did not start back up. I informed Approach that I had no engine power; [requested priority handling]; and squawked XXXX. I then executed the forced landing checklist and landed with no power at ZZZ on Runway X; with around 9 gallons aside. When I was on the CTAF and landed; the operator of the plane told me to try turning the plane back on with the left mag only; and the plane turned on as if there was no problem. Shortly after; we had an A&P look at it and decided it was the ground for the right magneto was making the magneto misfire at the wrong time.
