Acceleration lost while passing!!!

[Bcryan]

Twice in the last two days when I step on it at 45mph the first shift is fine then the second one dies right out for about 15 seconds before it gains RPMs.. I get caught barely passing a car on flat road. Any ideas?

I have no ideas at all , mine pulls strong no matter what speed I’m going .

I have the 3.6l v6 and I noticed a similar issue twice where once when accelerating up to about 45 mph where it just stopped and struggled (almost like a slipping gear shift). It is going in this Saturday to be looked at...not even 6 months old lol
