Try replacing the battery and if that doesn't work replace the logic board.

+...I would definitely start with the battery. After that there are a few more things you can try before you start replacing a logic board....

ok thanks but why do you think its the logic board ?? the phone just runs fine and its far too expensive to exchange a logic board on a 3gs i just paid 214 euro for mine

Try replacing the battery first and that will probably fix it.
