chrysler concorde 1999 problem

I have chrysler concorde 1999 3.2L Lxi the engine has been working ok
and I have been doing my oil changes before time around 4000K to keep
a smooth ride. Yesterday I parked my car and went in for grocerys and
came back to find out its not starting at all. I tried to start it for
about 5 mins but no response. I opened the hood took my engine oil
stick out, put that back in and it started working all by itself. Does
anybody has an idea if this is an indication to a bigger problem to
come in near future.
