vehicle runs great until outside vehicle tempature get hot 90-105 degrees. Then have power loss, sometimes stall and hard to get started. Thanks Ernie

get it scanned to see if any codes have stored. then check the ohms in the crank and cam sennsors as they will go bad and not give a code. try changing your fuel filter.
