Ford bronco ii shutoff

[Chris123]

I have an 86 ford bronco ii and it runs fine until it reaches its running temp. Then just shuts off untill it cools back down. I have replaced ignition coil just now and the problem still exists. Any ideas?

any codes?
have you checked your battery? your grounds?
fuel pressure?

which motor? 2.9? have you done a tune up recently? rotor and cap?

TFI ignition system can have a real issue with heat, so of course they put it in almost the warmest spot in the engine, surprised they didn't just strap it to an exhaust manifold,

Anyway have a look here, GOOD work sheet:

Someone suggested putting a bag of ice on the module after a no start/stall, and then see if it would restart faster, just to see if it is the module, and no DO NOT spray it with water.

Mine would do that. The fuel relay was bad.
