Have you checked the ground lead?
Make sure it is clean, it runs down and bolts to the top right hand side of the crank case.
Sometimes what happens is, that lead gets grime on it, oil or corrosion.. and it doesn't make good contact. The lights, spark ETC load the crank case and frame full of DC.. when you shut the bike off the dc cant flow through the starter so it won't turn over.
after a while the dc trickles out it will let the bike start again.
Hope thats it and it works for you, good luck!!
P.S. how is he liking his ace?? Awsome bike, I have had mine since 1999, and it not about to go anywhere!!

Remove the water trap bowl at the bottom of the petcock, (gas valve). Any water or trash in the bowl? Drain a cup of gas from the tank. Any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).
Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plug and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.
Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the two screws on the outside throat of the carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. Set the idle speed with the idle screw. This process should get you back on the road.
Since you mentioned uneven idle revs, be sure the carb and manifold are on tight and also tighten the cylinder and head. Air leaks can screw up the idle.

If they find nothing wrong then the problem is obviously intermittent and can be very hard to find. Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral wire connection.
The usual source of intermittent loss of spark is the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. Check for a broken wire at the switch or coupler. Get a service manual and check out the electrical section. Some bikes have a diode controller integrated into the turn signal relay. Try moving the kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it. If that doesn’t work, check out the relay.The dealer would / should have load tested the various ignition components. I will assume the ignition system is okay. Check the battery and fuses. Install a new set of stock spark plugs.
