1998 GMC Jimmy Had a new fuel pump and wiring harness installed

1998 GMC Jimmy Had a new fuel pump and wiring harness installed 4th july last year. Ever since (hot Days ) 80degrees or above outside. when driving on highway or at least 55 miles per hour for at least an hour when I brake for traffic or a light and come to a complete stop the vehicle stalls and won’t restart for at least 30 min to 2 hours and then it runs fine. No Problems encountered over the winter time and then today first hot day in michigan same problem….any ideas? No codes could be found when taken to shops.   someone said faulty fuel pump wiring harness overheating?   But why would it restart? Or something to do with overdive on the transmission as it stalls or cuts of and wont retart until it cools off????   Thanks in advance again this only happens when the outside temp is 75 or above out I guess…. No service engine lights illuminate or any diagnosis codes are stored
