Hello,
It sounds like you could have an issue with the crank position sensor.
If the crank sensor becomes defective it will not send the correct signal to the ECM and the engine might not start when that happens.

Typically with a faulty crank position sensor the engine light will get triggered.
Is your check engine light illuminated?
Scanning the vehicle for codes can help diagnose the issue.

On this vehicle, in order to replace the crank position sensor you will have to remove the timing belt.
I have attached diagrams for your reference.
Please let me know of any questions.
Thank you.
