ive been having a very odd problem with my gt lately, the other day i was driving to work and a warning came across my hud that said failsafe mode ok, the car wouldn't let me rev higher than 2900rpm and would barely crawl to 50mph, so i pulled over and restarted the engine and everything worked fine, i might add that it was around 20degrees outside, this morning i was driving to school in a snow storm and the same thing happend only this time when i restarted the car a check engine light came on, the engine kept stalling out and lossing power but the idle never dropped and it never fully shut down, it almost seems like it wasnt getting fuel for a breif moment, but then it would run fine again. i drove home with the check engine light on and the car ran fine and only lost power once. i had noticed that the past couple of months the car seemed sluggish and slightly less responsive than before. but i assumed it was the spark plugs since ive heard these are high reving engines and usually need new plugs around 30k miles, its an 05 gt with 32k miles. has anyone else had this problem, or do you know what failsafe mode is. my dad had a saturn with the same problems years ago and it was the ignition wires so i was wondering what the culprit was i know fuel pumps tend to go out on mustangs but im not sure what to make of this any suggestions would be great before i take it in
