Default missing when warm

hey guys thanks in advance for any advise. Here whats going on with my 92 coupe. Starts up and runs fine when cool, as soon as it gets to temp it misses badly and will stall. If you let it cool back down it starts and runs just fine until it gets back up to temp. The car has 140,000 miles but was well taken care of by the previous owner.

Just went thru this with a '92, but it had a DRENCHED Opti....and was rotted inside! Others have said ign module or coil and the coil wire can fail. When it's missing, try blasting air to cool them, see what happens

Any codes?

Sounds like fuel pump to me,

I had same kind of issues, Would run fine when it was cold, But everytime the fuel pump got warm/hot, it would start acting up & would die..... I would Let it cool for a bit & would run fine, Till the pump got hot again.. Then start all over again...

Just a thought,

Ant...
