is my 355 a lemon?

haha i think probably all ferraris are lemons in one way or another.
i just spent 10 grand getting the major service, and clutch etc done about 6 mo ago.. some problems started last week. if anyone can shine some light on it before i send it to the dealer id really appreciate it.

last wed.. i was driving home from getting some wheels installed at a shop 60 miles away. the drive up was fine and the drive back was fine however when i got on the exit ramp, my air bag light came on then both check engine lights came on and all the dash lights started to go dim the car starts to act like its going to stall. finally just as i pull up in front of my house the car dies. 10 minutes later i come outside, start the car, and it runs just fine as if nothing happened. some people on here told me it was the grounding strap some say its the alternator....anyway i stopped thinking about it since the problem didnt come back....
later in the week i wash the car and drove it around the block and it still runs great. 2 days later when i started the car i noticed that its running rough and it backfires and runs really bad but none of the dash lights were on. the car still runs and sound fine but it feels weak. i thought maybe its because water got in the wrong places, but it should be dry by now since i ve driven the car around. as i was nearing the end of the drive. i noticed that the check engine 5-8 light came on and stayed on. the only other thing i can think of is, i did check the air filter on the drivers side which has the air mass flow thing attached to it after i washed the car that day befor the car started to run bad and backfire. i am at a loss and i am about to get the car towed to atlanta which is 350 miles away. unless someone here can tell me what the heck is going on.
