Twice now I've gone to start up my AW11, had it crank a few times without starting, then suddenly stopped cranking. The first time it started up fine a day later and was fine for about a week, until this morning when the same thing happened again. I've replaced the ignition coil, wires and plugs all within the last few months, and the starter about two years ago. The car was sitting for a year and a half until mid-October of this year. Any ideas?
