Why does my Ford Country Squire wagon shut off while driving?

Short answer: A Country Squire that quits like the key was turned off, then restarts after it cools, very often has a failing ignition module. Ford's modules of this era were known for failing when hot. Check for a rusted transmission crossmember too, since that can let the transmission sag.

Symptom: The engine stops suddenly with no sputter, then may restart right away or only after sitting. Or the transmission crossmember has rusted away.

What to check first

1. Run your VIN at nhtsa.gov/recalls.
2. When it dies, check for spark right away.
3. Have the ignition module tested hot if possible.
4. Look under the car at the transmission crossmember for rust.

Likely causes

1. Ignition module failing when hot. Fords of this era use an ignition module that's known for failing when it gets hot. The engine just stops, and may restart after cooling.
2. Rusted transmission crossmember. The crossmember holds up the back of the transmission. If it rusts through, the transmission can sag.

What it usually costs

Owners in these threads didn't post prices.

Is it safe to keep driving?

An engine that shuts off while driving can leave you stalled in traffic and with heavy steering and brakes. A rusted crossmember is a safety issue. Fix both before regular driving.

DIY or shop?

The ignition module is a DIY swap on many of these engines. The crossmember can be DIY with a good jack, but rusted bolts may need a shop.

What owners report

• In 87 ford country squire wagon on Car Talk, an '87 Country Squire would shut off while driving as if someone turned off the key. Sometimes it restarted right away and sometimes only after sitting. A member said the ignition module is the first thing to replace, because Fords of that age were known for modules failing when hot.
• In 1989 Ford Country Squire sw on Car Talk, a 1989 Country Squire (5.0 V8 and AOD automatic) had a transmission crossmember rusted off on the passenger side. A member explained the basic swap: support the transmission with a jack, unbolt the mounts and frame bolts. The owner found the exhaust and converter in the way.

Quick tip

Carry a spare ignition module in the glove box on these old Fords. It's cheap insurance.
