2014 TRIUMPH TROPHY Engine Problems

THE DAY AFTER BUYING MY BIKE, IT COMPLETELY SHUT DOWN ON ME 4 TIMES IN SUCCESSION WHILE RIDING. FIRST ON A SURFACE STREET AT ABOUT 30MPH, THEN ON THE FREEWAY AT 65-70MPH, THEN TWICE ON THE SHOULDER OF THE FREEWAY AT LOW SPEED JUST TO GET IT HOME (ALL ON THE SAME DAY). THE DEALER INFORMED ME THIS BIKE HAD BEEN SUBJECT TO A RECALL INVOLVING THE REPLACEMENT OF THE ECU PRIOR TO MY BUYING IT, AND THAT THE REPLACEMENT HAD BEEN COMPLETED. AS OF 7/7/2014 THE DEALER STILL HAS MY BIKE, AND HAS NOT DETERMINED THE CAUSE OF THE PROBLEM AFTER DOING, IN THEIR WORDS, "EVERYTHING WE CAN THINK OF", TO FIGURE IT OUT. THEY HAVE TOLD ME I HAVE 2 CHOICES; 1) LEAVE THE BIKE AT THE SHOP UNTIL THEY DIAGNOSE AND FIX IT, WHICH OF THIS WRITING IS NOW 16DAYS; OR, 2) TAKE IT BACK AS IS....
