Today when I was driving home on the highway and pushed the gas in order to pass someone it was like the engine cut out so i took my foot off the gas and slowly accelerated and everything was fine. This is the second time in 2 days it has done this. Happens when in higher rpms. Anyone have any ideas what it could be? I have a 2005 King Ranch with 74,000 miles on it with a edge programmer, gotts mod, and magnaflow exhaust. Any help would be appreciated.

 

Any ideas? Need help! I dont want to drive it incase its something I will mess up more
