Default Trouble with 78 400

It's a LTD with new distributor, plugs, wires, carb, ICM, fuel pump and gas tank. It runs until it gets hot then it sputters and stalls. Any help would be great. The smog pump is bypassed.

Generally,, during heating or extended driving the ICM would fail, causing a no start/stall condition. After some cooling, a restart would be possible and likely.
Although more rare or less cause, a pick up coil could would drop out, or loose signal with similar affects..

I believe that came new with the distributor unless we are talking about something different.

Distributor wasn’t mentioned prior,, EGR application shouldn’t be at idle, although easy enough to prove out..

Unless the EGR is open/bleeding removing the vacuum hose will eliminate EGR application.. The temp doesn’t seem to follow EGR,, So,, hot meaning what?

Hot meaning running temp. Could it be the carb is to rich when it gets warm and is flooding it out.
