Engine cuts out while driving

I have a 1994 GT with about 150k on the clock. It just developed a new but infrequent problem. I'll be driving along and suddenly the tach will flat line to 0, check engine light will come on, and then suddenly the engine comes back to life again. It happens so fast that I can't tell if the engine starts back up on its own or if I shifted and the clutch pop started the engine.

Any ideas what could cause this? Ignition switch maybe?

Sounds like it might be the stator in the dizzy. Its a small part inside the distributor housing that causes the sn's to cut out suddenly and randomly start up whenever it feels like working again. May be a minute, or 4 days. Its cheap and an easy fix.

Replace the dizzy dont just replace the pick up coil. Try not to geta remanned dizzy because the pickup can be good when they test it (cold) but once it gets hot in your car it s***s out

Thanks for the suggestion. I was doing some more searching last night too, sounds like the recommended advice for an sn with high mileage is to just replace the dizzy with a brand new one (not reman).

Exactly. A new OEM dizzy would be your best bet but if you have trouble finding one, the Summit Racing billet aluminium unit is a good substitute. I have 6500 miles on mine.

I've always just replaced the pickup in the OEM dizzy if the unit still spins well without any sqeaks. All has been good.
Plus its cheap, the pickups cost about 25 bucks and a new dizzy (especially OEMs when you can get them) are 125+ bucks.

I'll pull things apart and take a look. If the dizzy seems alright, I'll just replace the sensor. Thanks for the replies.

Your dizzy is 17 years old and it's gone well past its design life. I also thought my original dizzy would last forever until it started breaking rotor tips 'cause the shaft bearings had worn (it never squeaked so I had no warning). Replacing the PIP sensor and then getting stranded at the roadside a few months later with an engine that refuses to start (broken rotor tip) isn't fun, so it's a false economy just to replace the PIP sensor. I learnt that the hard way and you don't have to.

If the distributor checks out, check the ground strap from the engine to the body. I had a car do that exact same thing and found that the ground strap was loose. Fixed it for free!

Takes 2 seconds to do, but check the battery terminals. If they are loose, the engine will cut out while driving. You can rule this simple possible cause out fast too.

So will everything else that's electrically operated.

Jsut wondering if you ever fixed this problem?
Been having a similiar issue in my '95 and has gotten much worse in the last few weeks (I only drive the car every once in a while).
Did you change out the distributor or just the pick-up coil/strator?

Check the power cable going from the battery to the fuse box under the hood........these cars have a bad habit of this cable coming loose for some reason.

I just fixed this.

I had identical symptoms on my 95 with the same mileage. I just bought a NEW not remaned distributor. Problem went away, been 3k miles.

Sorry for not getting back to you guys. The problem is happening so infrequently still that I haven't wanted to spend the money on a new distributor. I don't doubt the advise given here, I'm just being cheap at the moment.

As a follow up I put in a remanufactured distributor about 3 months ago, driven the car a bout 1,000 miles and no issues thus far.
