Question SLK230 dies while running and randomly won't start

my 2000 SLK230 has been randomly shutting off, and just as randomly not starting on occasssion. it has quit while i was driving around 80mph, 40 mph and idling at a stop light. It will start fine fopr a week and then not start. after i keeep cranking (it doesn't actually crank, nothing happens) for a while it may start. Then an hour later it may be fine. I have had the air sensor and crankshaft position sensor replaced. Do you think it could be the fuel relay, or fuel pump?

Any codes? How old is the battery?

I'd also consider the K40 relay a possibility...
