Hi Fellow BMW owners!

Just purchased a new Sertao, I love the bike I think?? I have been experiencing issues with the bike starting? It only has 145 miles on the clock. The other day I went for a short ride, stopped for gas, and the bike would crank and not start. It took about 15 minutes of cranking, stopping, and then cranking to finally get the engine to fire. This has happened several times before. The bike would either not start initially then after a few minutes finally fire up or after riding and shut down, would fail to restart? I believe it is a fuel delivery issue or something to do with the ECM. The bike has been in the shop for the past 14 days, no word yet on cause or fix? Any suggestions, comments, ideas? I like the bike for the short time I road it.
