351W shuts down

351W shuts down
I bought this stang out of state from an used car dealership. When I first test drove the car it was great. It all started on the drive home. The car just shuts down, I ended up having to tow the car 900 miles to make it back to AZ from TX. It turned out the alternator was bad. I replaced the alternator and battery (since it was over 5yrs old). All was well for a couple of days of normal driving. Then one day it just died while going 35 mph. It cranked backup immediately and I was able to drive home without incident. A couple of days go by and no problems. Then yesterday after letting my brother drive it, and he got on it a little, it starting shutting down again. This time about every 3-7 minutes of driving. The car has no problems starting back up; that's what's wierd. It does this while driving or just sitting there idle. Here is the cars config:

Cobra 6sp leather shifter ****
18X9 & 18X10 American racing rebel wheels
Nitto NT555 265 35 18 (FR) & 285 35 18 (RR)
Things I've noticed before and after this issue happens
fuel pressure at 40 psi at idle and increases porportionally with pedal input
Vaccum at 10 in Hg doing 35 mph decreases with pedal input
water temp at 165 degrees when initial shutdown happens
smell of fuel when sitting in garage overnight appears to be real strong from passenger side engine compartment
Voltage at 14.5 when engine running (new alternator only 3 days old)
Battery Voltage 12 volts static (new battery only 5 days old)
Oil level good and clean
coolant level good
No check eng light on shut down, but I do get check eng light on occassion after driving it a few miles but not shut down (this was prior to the shut down issue starting) and the car appears to be OK
20K on motor
75K on chassis
Let me know if you need anymore info, this all I can think of at the moment. When I test drove the car before I bought it, it was fine and damn awesome. Right now it is my worse nightmare...having a unreliable Stang in my garage. I'm new to the 5.X motors, I came off the 4.6 bandwagon.
I suspect something in the ignition system. Fuel system appears to be OK when running. It seems to shutdown consistenly at approximately 3-7 mins running cold or hot. Help!!!!!!
Thanks. Dave

Well, I went ahead and ordered a new MSD distributor, coil and wires direct from MSD. I'll be picking up plugs today from Autozone and an ignition switch. I've had this car for 2 weeks now and really want to start driving the thing. MSD is out of El Paso, TX so I should have the stuff by Friday. I'll post the results after I swap out the parts. Wish me luck. Thanks for all the input.
