First off let me get too the mods in advance:
BBK longtube headers
Boss 302 manifold
BBK offroad x-pipe (problem occurred before and after install)
Roush Axel Back

Car turns off randomly, not often, but only when decelerating and while I'm on the clutch. When I turn the key, she starts right back up, even mid roll from the previous stop. Any hints or advice would be appreciated. Taking her down to the tuner tomorrow because of the new x-pipe. Thanks in advance.

Is the car tuned for the other mods? Maybe the tuner can help. Does it go down to like 400 rpms, hold for a split second and then stop?

yea the car is tuned for the other mods. She definitely drops to about 400 and then dies. Sometimes she recovers when she bumps 400. Keep in mind though, this will happen randomly. One time it happened to me 3 times in a single day, I've also gone months without it happening. Just kind of at a loss on what to do or where to start looking for solutions. i already cleaned the mass air flow sensor

We have a 2006 v6 mustang & it quit,s at random when decelerating after the car has been ran for a while also. We have only had the car for a year no ck eng, light or codes. I think it,s a chassis electrical issue it has happened about 20 times this summer nothing repeatable or consistentit,s my wife's car & she don,t like to drive it now because it quits. If I can,t solve this issue & she don,t drive the car I,m going to get rid of it & buy a vette

Try cleaning the MAF sensor and check for air leaks / vacuum leaks.
