1999 Chrysler Sebring Car floor holding water

Every time we get a hard rain my sebring rag top is taking on water, I can hear it sloshing around inside the floor body of the car it is getting wiring wet and shorting things out also if I stop too hard something goes wrong and the car spits and sputters like it is not getting gas it is ok after a minute or so as long a I do not shut the car off. The trunk is dry the spare tire well is dry but I can see water seeping up from bolt that holds drivers seat in and back floor on that side floods, no where else in the car. Is there a fix for this?
