Is the Houston heat choking truck?


#1

I live in Houston tx and recently we have been having really hot weather like mostly around the high 90s and every time I drive my 2003 toyota tundra v8 when I step on the gas petal it makes a fan noise and the truck feels like it has no power this only happens when I have driven it more than 30 min and only happens when it’s hot out what might be the problem? The truck has 73000 miles on it

Thanks
