My 07 Exec with 20K has been running like a dream until today. About two miles from home after a 40 mile commute from Austin the engine started to hesitate whenever I added power. Luckily made it home without stalling. The trip meter indicated 190 miles when I stopped, but the fuel guage showed the last segment still black but flickering. I usually exceed 50MPG so I wasn't out of fuel. Is fuel contanintion a possibility since the fuel was low? I installed new plugs at 18K and no indication of any problems besides the hesitation. Any ideas before I take it back to the dealer? Not sure about he local Suzuki Burgman mechanic, since previously he didn't know location of stopper bolt.
