I'm having a stalling problem with my 1980 + 8. SU carbs New fuel filter

It's happening after a short time after startup. Starts fine. Give it a little choke as it's cooling off here. Then choke off

It'll run fine for a few miles 3 or 4 and then it quits. Really hard to get it started again. Cranks but won't start. Then it'll start and quit Takes 5 or 6 tries Then it'll finally starts then it "stumbles" for a short while till it smooths out.

Someone has said it might be the coil.

Doesn't happen all the time.

Any advice ?
