wont run

What is your question?

it was really hot one day and the car just died.....wouldnt start back up. so i let it sit over night and the next day started up. did this a couple times. the last time it did this and started next day very sluggish. then it would start and stall. then i would give it gas and it would stall. if i gave it gas very slowly i could get the rpms back up but if i hit the gas normally it would stall. now it wont start at all. i need help.....
