Other Fuel System Tank Mounting problems of the 2004 Chrysler Sebring

Had fuel pump replaced a couple months ago. Then at gas station wouldnt start at all, had a tow truck take it to a mechanic and that mechanic tapped on gas tank and it started and said fuel pump needs to be replace so I called the dealer where I bought it because the new fuel pump had a warranty. They said they found nothing wrong with fuel pump but found problem wirh #2 selinoid and they replaced it. Two weeks later ths car was driving fine but when I got home and turned off the car for a couple hours it started right up. So I turned it off and on a couple times then the engine surged then hestitated then died. It did it twice after starting it then turning itvon about 5 times trying to find out what could be wrong with it. I bought the car in February 2017. I had both strut mounts fixed, fuel pump, an air valve from coolant do not remember exact name, #2 selinoid now this problem. I still owe on this car and its not reliable and scared to drive it and wreck.
