Trouble with mercedes benz c240

seemed like it didn't wanna accelerate I
was going about 15 mph and then it
dropped to less than 5 and was kinda
jolting forward. I parked the car for
about two hours started up still didn't
wanna accelerate normally turned it off
then turned it back on now it won't
start just makes a click sound.. any
