1976 MG Midget engine cut off while driving

Car had ran great all summer, have had a blast with it, but last week, I was headed home and it just shut down, like you hd turned the switch off, or like it had ran out of gas, car rolled a few feet , fired right back up enogut for me to get it off the road,,,, pulled it home, and thought my fuel pump had went out, but when checked it , it was pumping,checked the points and there was no fire on points,,,,,, put new points, condencor, new coil, and coil wire, fired right up , took it for a drive and it ran great, but upon returning home, cut off again, jsut like before , while still rolling it will fire back up, I did notice if I pull the choke all the out it will contuine to run enougth ti get it home....

Any ideas whats going on..

Thank you very much
