I have a 2000 mazda protoge 1.6L, a few months ago it would stall in the heat even though the engine was well within operating temperature. When this happened it would take ~10min to cool down and then restart just fine. A month ago it did this and then never restarted, it has no spark. I have replaced the crank sensor and the cam sensor and still nothing. Any suggestions? Im running out of options here.

Edit: engine throws up no codes.
