Have you noticed interior lights staying on or maybe a "door ajar" light in the instrument cluster coming on at odd times? It's pretty common for door switches to stick on this era of Fords, and such an issue could explain the security system going off.

I used a product Caig brand De-Oxit to clean my door switch (sprayed in the latches) and followed that up with Caig Preserv-It which took car of my 1998 SHO for a couple more years (at least to the time I sold it). For all I know it's still working fine.
