Yesterday I went to start my car and it wouldn't turn over. After playing it fuses it finally started right up, then 5 min after starting it up I was on the highway and the car shuts down and won't turn over. No clicking, just nothing. After 10 min it started again and I drove it down the street and it shut down again and I had to get it towed to my house. Went to start it up this morning then it started right up so I drove for 10 min and it shut down on me again and wouldn't start. Just got a new battery, water pump, all new hoses and my oil changed. Could it be my ignition?
I need help fast.

Hello,

This sounds like an issue with the crankshaft position sensor.
The crank sensor measures the rotation of the crankshaft and sends that signal to the ECM. Over time with heat and vibrations from the engine the sensor can lose its internal calibration. This will trigger error code to the ECM and the engine can shut down.
After the shutdown, the engine may or may not be able to restart.
The Crank position sensor is located on the back of the engine block, below intake manifold.

Here are some helpful articles:

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
