car dies then no spark
I have a problem with my mustang and i have tried sevral things and cant figure it out. The car runs good and is very strong, but when i get on it hard and the car is hot ( actually normal at about 160 degrees) it shuts off on me and it wont start for a while. it only does it when i step on it hard over 4000 rpm. It will drive normal all day. It has no spark from the coil, until about 30 minutes pass by. I have changed the coil Cap & rotor, and wires all new from msd. I thought it might be my msd box so ran the car without it and it does the same. Also tried another dizzy that works for shure it was in my friends running car.. Has this happened to anyone or any advice would be appreciated. thanx. Im starting to think its an electricall problem. My next step is getting a new wire harness since i am so fustrated and have tried evrything i can think of.
any help pplease.
im despreate havent enjoyed my car in over a year. i have took it to 2 shops (where they specialize in mustangs and even they cant figure it out)

There is more to then what you think. Before you start slapping random parts do the proper diagnostic procedures. Follow these step, this guy knows his stuff

Also it could be very likely the Ignition control module could be out. Pull out and getting tested.

computer overload
If you changed everything related to spark, like coil, dizzy, modules, etc. I will go out on limb and say something is causing a computer circuit to heat up and shut down. I would suspect your vss sensor is bad and the the vss wire and plug is shorting out at 4000 rpm and above causing the computer to shut down.

How in the hell would a speed indicating mechanism cause any kind of fault that would be directly related to engine RPM?
