Went got gas this morning left station while driving car seemed to want to cut off stop at light cuts off it starts up but as soon as u put in gear it cuts back off what could this be

Replace fuel filter and add fuel injector cleaner to gas tank and use middle grade or high test gas to help clean out the gum and carbon build up

If this just started when you got the tank of gas, go back to the station and ask if there were other complaints of bad gas. Sometimes water gets into a tank and if the tanks is getting low, water may be pumped into your tank. The gas company should pay for any repair necessary. You can add an additive to the tank to neutralize the water, but depending how much, the tank needs to be cleaned as do the lines, injectors and filters. If you have a very big, ugly, mean male acquaintance, he may help them understand your dilemma.
