NOT happy with the X...

[houdaman]

Hey guys, i took a trip down to Seattle this weekend.
on the way there, on the I-5 doing about 80km(getting on a on-ramp), The X stalled for a quck sec., yellow ! light, abs, trac control, and ENGINE FAILSAFE PROG appeared.
I shut off the car and restarted it was normal...until another 5 min and same thing happend when STOPPING.
the lgihts went off and i continued to drive, and I went to pass a car and when i floored it, my check engine light flashed and stayed on.

I got to the hotel, and took on and off the connections to the battery and it was all fine, until on the way back home same situation; I depressed the accel to the floor and check engine light was blinking and then shut off...
