G.E.D.R.

i have a ? on my 95 trans am.. i went to arbys to get something to eat car ran fine all day the i parked to get food went back out it wouldnt start. i tried the battery cause the gauges arent working the battery was fine so i thought maybe the starter it was fine too gauges still arent working and the car stilll wont start i can turn it over by the crankshaft but other than that engine wont start.was thinking it was maybe a security feature or something anyone out there have any suggestions they are greatly appreciated thx
