Why does my car turn off when it warms up?

As the engine warms-up and starts burning fuel more efficiently, the choke plate begins to open, which slowly lets more air in and leans-out the air/fuel mixture. ...

What would cause engine to shut off while driving?

A lack of fuel pressure or fuel volume can easily lead to engine stalling. Common culprits include a faulty fuel pump or fuel pump relay. A clogged fuel filter or bad fuel pressure regulator is also common on return-type fuel systems. Another often overlooked problem is the vehicle simply being out of fuel.

Can a coolant temp sensor cause stalling?

What sensors can cause stalling?

Some of the most common sensors responsible for engine stalling include the engine coolant temperature sensor (ECT), mass airflow sensor (MAF), and throttle position sensor (TPS). Additionally, issues related to a vehicle's throttle body or idle air control valve (IAC) can also induce a stalling condition.

Do bad spark plugs cause stalling?
