While driving around 75 mph on the Interstate today the car stalled out on 3 different occasions. That was the first time this happen and I've had this car since 2016. also I've driving on a 2 mile dusty road everyday for the last 4 months.

Hi,

The dusty road could definitely be effecting this so we need to address it first.

Start with changing your air filter and then clean the MAF sensor and the throttle body bore. If this is getting dusty then it could effect the performance and cause the stalling.

Once this is performed we need to retest it. If it still does it then we need to check fuel pressure while driving. If the fuel pump is beginning to fail then this can cause this as well. You can just hook it up and then tape the gauge to the windshield so you can see it while it stalls.
