Narrative:

I was cruising at 10;000 ft altitude to return from consulting out of town. I was between layers in a very dark sky. No stars; no ground lights.I was running the starboard engine on the nearly empty aux tank; waiting to change to main tank when the fuel pressure dropped.the engine lost power; I switched the tank fuel valve; engine stopped. I waited for the engine to regain power; but nothing happened. I couldn't see the prop as it was too dark. I assumed that it was windmilling as our training practice engine outs usually had difficulty stopping the windmilling.I concentrated on keeping wings level and the speed up. I gave full power to both engines. I did not feather as I knew that the engine should start up.center called me stating that I was off course and had lost nearly 3;000 ft. I informed [center] that I was having some difficulty. They asked if I needed assistance; or needed to declare an emergency. I said not now; I'll call if I need to. They informed me I was 10 miles from the nearest airport.I finally was able to see that the prop was stopped so I hit the starter and the engine started. I informed center that I was going to climb back to 10;000 ft and continue.the remainder of the flight was normal.

Title: A C-310 pilot intentionally ran a fuel tank dry but the engine did not restart after available fuel was selected. So; after losing 3;000 FT he used the engine starter to regain power and return to his filed altitude.
