possibly water in your fuel.... it's a small tank so just put about a quarter bottle of gas line antifreeze in the tank... it's alcohol so it will **** up the water. there is also the possibility the fuel is somewhat dirty... change the fuel filter as well

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!!
SOURCE: 2006 Yamaha TTR 50E pouring oil out of air cleaner housing
With the oil problem I read on another site that Yamaha did that so that excess oil would be burned up in normal running (but this was usually smaller amounts). Anyways they disconnected the tube going to the air cleaner and had tied up in such a way that any excess oil would land on the chain thus lubricating it. But if you have that much oil coming out it could be that you have put in too much.
