I HAVE PROBLEMS WITH MY 92 MAZDA 929. WHILE DRIVING ON THE FREEWAY AT ABOUT 80MPH THE ENGINE JUST STOP. NO LIGHT CAME ON OR NOTHING I TRIED TO RESTARTED AND IT WOULD NOT DO ANYTHING. ITS BEEN CHECKED FOR ELECTRICAL PROBLEMS ALREADY AND ALL THE NO BRAINER STUFF(I.E. SPARKPLUGS OIL ETC. WHAT ELSE COULD OF CAUSE THIS. I AM RUNNING OUT OF IDEAS HERE.
ANY FEEDBACK WOULD BE GREATLY APPRECIATED IT.
THANKS

IF YOU ARE SURE THAT YOU HAVE GOOD SPARK & FUEL PRESSURE; THEN CHECK YOUR TIMING BELT, IT MIGHT HAVE JUMPED
JUST ENOUGH TO GIVE YOU THE NO START CONDITION.
