5.0L V-8, Electronic Fuel Injection, 79,000 miles, 2 WD, 4 speed manual. I’m the original owner.
If I drive it 4-5 miles on secondary streets (25-40 MPH) it shuts off without warning after 10 minutes and will not restart without a 20-30 minute wait. If I drive it 2-3 miles and park it for a couple of minutes it will not restart without waiting 20-30 minutes. Checked engine water temp gauge and it is normal.
The local mechanics found no spark when it failed at their garage. They replaced the ignition module on distributor. This did not fix the problem. In their second attempt they replaced the coil. Still the same problems persists and the mechanics are stumped.
It’s like something in ignition package heats up after 10 minutes and either sticks open causing no spark or closes shorting out the spark if that is possible.
Any ideas on what is causing this and how to fix it. Thanks – Glen
