Intermittent loss of power and shutting off

Hello,

Does your vehicle has issue with the idle? Does it act erratically when you have the issue?

Is your check engine light on?

You could have a dirty Mass Air Flow sensor, which acts out in certain conditions.
When the MAF is in operation intake air from the engine passes through it which has impurities which are not removed by the air filter such as heavy air practical's. Over time these impurities cause a condition called "coking" which develops on the sensor "hotwire" which inhibits the sensor's ability to send accurate feedback data to the computer which can cause low power, low idle, hesitation and even stalling
