My first guess would be the crankshaft position sensor I have replaced a lot of them for that concern on that car. Sometimes they set a code sometime they dont if you had a scan tool read live engine data for rpms. When it wouldn't start you could see if the rpms were reading while cranking if they wernt most likely a bad sensor. The only other way would be to take And measure the ohms reading of the sensor when it wont start. When they go bad they will read as a open no value.A good one reads like 800 ohms or so.
