Runs when cold, not when hot.

Hey guys, might you know what would cause my 95 ace 1100 to suddenly die after it gets hot? It has strong spark at cold, but have tested the plugs once hot, and none of them will fire.

Possible heat failure of the ignition control unit . If you get it running while cool, heat it with a hair dryer to see if it will cut out. Tap on it too. Spray water on the coils and see they arc anywhere.

Start up in a dark garage also a good way to check for arcing.
Don't let it run too long without some kind of ventilation in the garage/shed.

Sounds to me like the coils might be cracked. That will cause the bike to die after it's heated up, and the crack has separated enough inside so that the arc can't jump across the crack anymore, and it won't start again until it's cooled enough for that gap to close and the arc to be able to jump across again. Had that trouble on an old Sporty I used to have. As soon as the coil was replaced, it ran like a champ all the time.
