Does it shut off like instantly or does it stumble a bit and then die? Does it restart immediately or does it have to crank for a bit? By GO do you mean only when you floor it suddenly? What engine do you have? Can I assume that you have ALOT more audio equipment hooked up than the normal person does? What has been replaced to try and solve the problem?
Sorry about all the ?? but your original post is VERY vague
It shuts off like you turn off the key, no stuttering or struggling. It restarts immediately with out any trouble, less than one crank. GO>anything more than easing on the accelerator slowly to get up to speed. It is a 5.2 with 40k on it. Replaced parts:
Tranny and TC, 3 times
Exhaust (the whole exhaust) 2wice
Brain
Air Intake Ctrl unit 2wice
fuel pump and lines
plugs, wire, cap, rotor
MSD starter and ignition system
Battery and terminals
Engine harness
Alarm system (just in case it was the kill start safety security feature)
Other stuff that does not contribute to its running, but what the heak:
Brakes (every aspect of the brake system)
shocks
tie rods in and out
ball joints
wheel bearings
head gaskets
no sound system yet. that is this weekened
