Default 1979 F150 Ranger

Good evening fellow Ford friends. I have a 79 f150 4x4 with a 400m motor pand love my truck. Coming home from camping trip this weekend she died twice on the freeway. I had here towed home. When I looked under hood I saw some smoke coming from back of motor. I thought maybe bad egr valve. Today after removing egr valve I notice this part -picture attached, does anyone know what it is?

thanks for any input.

Sanddoc, thank you for the response. It seems to cut out and die when I am on the freeway. I have replaced the ignition coil but have not had a chance to test it on freeway for any reasonable distance yet. I hope to do that this week. The carb was recently rebuilt and a new fuel pump was put in so I am leaning towards spark issue and not fuel. The ignition coil was the only item that I had not replaced in the last year or so. I will post update later this week after my test run......fingers crossed.
