My 05' went to FAIL SAFE MODE. Wife was stopped in traffic waiting for bridge to close. Duration of about 10 min. It was at idle in park. I don't recall seeing check engine light.

Turned off and restarted, message cleared and car ran normally. Dealer said there was a code stored. P2104. Said they talked to engineering and were told it was some kind of advisory message. They ( engineering ) wanted to know if the car had been modded. It has none. Actually it must be the only BONE STOCK mustang on the planet.

Anyone else run into this?
 
I had this happen a couple of times last summer on my stock 05 gt. The car ran fine and the fail safe mode would go out when I restarted the engine. It turned out to be a connector on one of the wires going to the injection system. (I don't know which one) The first dealer I took it to said they couldn't find the problem. The second dealer found it right away, recrimped the wire into the connector, and I haven't had a problem since.
