Hello there!
It sounds like you're dealing with a tricky intermittent issue with your Sonata. Since the car starts after about 45 minutes, it might be a heat-related problem. Here are a few possibilities to consider:
1.) Crankshaft Position Sensor: Often, when this sensor fails, it can cause the engine to cut off and not restart until it cools down.
2.) Fuel Pump or Relay: If the fuel pump or relay is overheating, it might cut out and prevent the car from starting until it cools down.
3.) Ignition Coil: Similar to the crankshaft position sensor, a failing ignition coil can cause intermittent starting problems when it gets hot.
4.) ECM (Engine Control Module): A faulty ECM can sometimes exhibit these symptoms.
Since the problem doesn't show up at the shop, you might need to try and replicate the issue yourself. Next time it happens, consider these steps.
A.) Check for Spark: When the car won't start, check if there's a spark. If there's no spark, it's likely an ignition-related issue.
B.) Listen for the Fuel Pump: When you turn the key to the "On" position, you should hear the fuel pump prime. It could be a fuel pump or relay problem if you don't.
If you’re able to identify whether it’s a lack of fuel or a spark, it’ll be easier for a mechanic to narrow down the issue. Otherwise, a reputable shop should be able to perform a thorough diagnosis, focusing on these components. Don't hesitate to mention these possibilities to your mechanic to guide them in the right direction.

Good luck getting your Sonata back on the game!
