2000 Mazda MX-5 Miata

AFTER DRIVING AROUND IN HEATED CONDITIONS (ROUGHLY 80 DEGREES OR MORE) FOR ABOUT 10+ MILES, SOMETIMES LESS, THE CAR WILL NOT START. IT WILL CRANK AND ATTEMPT TO START BUT FAILS TO DO SO. IN ORDER TO GET IT TO START I HAVE TO POP THE HOOD OPEN AND LET IT SIT FOR 10-15 MINUTES. ONCE IT STARTS IT IS VERY ROUGH AND THE CHECK ENGINE LIGHT WILL COME ON. IF I STOP DRIVING IT FOR THE DAY, THE NEXT MORNING, THE LIGHT WILL BE OFF AND IT WILL DRIVE FINE, UNTIL I DRIVE DURING THE DAY, OR OVER A LONG DISTANCE. THRE HAS ALSO BEEN AN INSTANCE WHEN I WAS DRIVING AND STOPPED AT A STOP LIGHT AND THE CAR JUST STALLED, HAD TO PERFORM THE SAME THING, POP THE HOOD AND WAIT, IT WAS BACK RUNNING. THIS ALSO HAPPEND AT A DRIVE THRU IN 100 DEGREE WEATHER, CAR STALLED AS SOON AS I GOT MY FOOD AND HELD UP THE ALREADY LONG LINE OF CARS BEHIND ME. I HAD TO PUSH IT TO A NEARBY PARKING LOT. I HAVE READ ON NUMEROUS FORUMS AND POSTS THAT THIS IS A COMMON PROBLEM WITH THESE CARS AND THAT IT'S EITHER A) IGNITION COIL B) SPARK PLUGS C) SPARK PLUG WIRES OR D) CAMSHAFT POSITION SENSOR.. WELL.. I CHANGED OUT THE FIRST 3 OPTIONS, WITH NO SUCCESS.. STILL HAVING THE SAME PROBLEM. I RECENTLY BOUGHT A CPS AND WAITING FOR IT TO ARRIVE. IF THIS DOESN'T FIX THE PROBLEM I DON'T KNOW WHAT WILL. I DRIVE CONSTANTLY ON HIGHWAYS TO GET AROUND AND IF IT STALLS THEN, I WILL BE IN A LOT OF TROUBLE. I DO NOT HAVE A WARRANTY SO I AM DOING ALL THESE REPAIRS MYSELF.

CAR CONTINUES TO HAVE "CHECK ENGINE LIGHT". DEALER INDICATED 3 WEEKS AGO THAT THERE WAS A FAILURE IN CYLINDER #3, BUT THEY WILL NOT GET ON WITH THE REPAIR. DEALER HAS CHANGED SEVERAL ELECTRICAL PARTS, CATALYTIC CONVERTER, AND LAST WEEK SAID THEY WOULD REPLACE THE ENGINE. NOW THEY ARE BACKING OFF ON THAT AND PLAYING "TESTING GAMES".*AK
