2012 Chevy Malibu this car is setting off after driving for about 10 minutes then you let it cool off it will start up . After much research online I didn't find anything helpful But I found this myself the relay for the field pump what extremely hot after a 20 mile Drive. So I popped the fuse Box down found that 1 of the wires was very loose connection I want to the Junk yard and found a replacement terminal/wire. I soldered it in. Then preventing back together and drove for 30 miles in the hot part of the day when I got back The relay was not hot at all.
That excessive heat was causing a loose connection to the fuel pump.
