2001 Fleetwood Expedition DP chime in overhead.

My 2001 Fleetwood Expedition will sometimes start a chime or ding every few seconds while I am running down the road. It starts and lasts from a few minutes too an indefinite period. I have stopped to try and find it but it goes away when I start to stop to check. Its is a chime that I have never heard otherwise so cannot pin point what is could be. Any suggestions would be appreciated.
