odd engine behavior

Took the Stang on it's first interstate weekend getaway this weekend. Ran about 2hours up to Canton GA, north of Atlanta. Overall, The car ran great, cruising at 80-90 in the HOV through town. Scarily enough, i was mostly running with traffic.
I had a strange thing happen twice, however. The first time I was headed up Sat, had been cruising 75-80, and downshifted to 4th to get around a slower car in traffic. After the clutch was fully engaged and I was accelating smoothly, it was like the throttle snapped closed for a split second. Even my wife noticed. I thought maybe the AC kicked on or something, but it was a significant punch, nothing the AC should have done.
Coming home yesterday, I had been running 80 coming through downtown and suddenly had to come to a near stop for a wreck. I got down in 2nd and accelated away from the initial slowdown, and it did the same thing again. Clutch was fully engaged, foot away from the pedal, and accelarting briskly, around 3500 rpm. It was a hard, splitsecond, loss of power. It happened so fast I didn't catch if the tach dropped. It was more significant than a cylinder misfire.

I haven't been able to recreate it, and it hasn't happend before.

Anybody else seen this? I got the distinct impression It might be tied to the ETC?

Be Careful!

hey guys,
same thing happened to me on a roadtrip from D.C. to Mobile and back. I was a little worried and thought maybe i hit the rev limiter until the whole rear end shreded while on the hwy two days after i got back! smoke billowed from the rearend and it wouldnt shift. towed it to the dealership(century ford in MT. Airy,MD) and they hed to put a whole new rearend in it. Be carefull and have it checked. The mechanic said he was going to try to rebuild it until he opened it up. It took over a week to get the new rear from detroit and install it.
it happened right at about 5300 miles. guy said the pinion had not been installed correctly at the factory. also, make sure they put the brakes on correctly afterwards. mine were popping and had to bring it back in for a day.
On the good side, the dealer has been great to me and i didnt even buy it there. nice guys.also everything is covered under the warrenty. havnt had the problem since.
hope this helps
