Re: Justs quits running
Modules can fail as they warm up -- especially Ford types. Most fail hot, but that's not a rule. The quit when they feel like it.
First you need to determine if it's spark (a lack thereof) or fuel.
Since you say it's a sharp cut-off, not sputter-sputter- die, then I'd suspect the module.
Next time it happens, check for a spark. If none, try a new module. Even if that's not it, it will be someday, then you'll have a spare.
Check the routing of the coil wire too - don't let it touch anything - look for whitish marks on it where it's been jumping through.
