87 ford country squire wagon

lately this car will just stop when i am driving it. Like someone shut off the key. It doesn’t sputter or cough or clink. It just stops running. Sometimes i can start it back up immediately. Sometimes it won’t start and i have to push it over to the side of the road where after awhile i can start it again and drive off. any ideas

I can tell the first thing I would replace for this problem is the ignition module. Fords of your vintage were notorious for these modules failing when they got hot.

i,ll give it a shot
