It was hot 108 degrees . iwas driving then bam ! It felt like i ran over something. Then everything turned off . then the car turned on . but i had no lights no dash lights..no power windows . but i could still drive ibut it didnt have the power it normally had. But i was able to get it back home the whole time it kept flipping on to normal with lites and power then back off. With no lites and no power and ran slow like it wasnt running on all cylinders. It did it once before when got really hot over 100 degrees

Almost seems like your battery is possibly dying. Check your voltage after sitting overnight and do a load test. Post your voltage here after sitting overnight, and while alternator is running. It does seem power related though. I have known batteries which are dying or have little fluid left in the cells to die on very hot days.

Much of my time during the job is spent hauling things up and down the stairs to the basement or in and out of the storage shed, or running back downstairs when I realize I need something else,or taking a break from standing out in the sun,or using flashlights or work lamps when it gets dark.

mine did similar on a very hot day, the ECM was over heating.
It helps to run the A/C as the cooling fan in the computer box draws its air supply from inside the cabin.
