when ever it wants to it does not start. dash light come on headlights etc. i checked all the fuses starter & relays. All fine. it will work fine for weeks or months, then out of nowhere it does it again. once i could'nt get it to start for a week, then one day it started. now yesterday my wife had the problem & was stuck at a shopping center, while i was at work 50 miles away. she tried severl times while walking are dog in between. i took off early & when i got there she was'nt there, so i used my key (not a passkey) it fired right up. i called her she was about a mile away i pick her up in it. she was blown away. se had been stuck there for 2hr. now she's affraid too drive it.

Really need to have the security system and the starting system diagnosed. Just because the starter seems to work during a test does not mean it isn't intermittently malfunctioning, this is common. If you get a shop to scan your security system, there will most likely be some codes that will lead you to the issue.
