Talk Morgan Forums Thread Like Summary - Loss of power and cutting out when driving

I've a 1972 4/4 1600 and when driving for a while (say after 30 mins), the car starts to lose power and then cuts out. After 20-30mins, it will start again (with a struggle) and go for another 10-15 mins before the same happens again. I've replaced the coil a number of times, fitted an electronic fuel pump, new distributor, rotor arm and alternator, but this hasn't solved the problem. I left the car running at home for over an hour, but cannot simulate the issue, although I did not that the coil was hot. Has anyone experienced this problem and found a solution?

I had similar issues on mine a few years ago, i thought it was fuel, checked everything, no.

Working on ignition, I reverted back to points & condenser with a new ballast resistor,from the lumenition, changing HT leads, plugs & coil.
Most of these are cheap enough on a 70's 4/4!

After a process of elimination, I finally found the problem to be a hairline crack in the distributor cap, which caused the issue once the engine was hot.

Good old Lumenition back in play as that wasn;t the issue and far more reliable than points in my experience.

It may not be the same issue as yours, but just keep working through component replacement until you find the cure.

Good luck!

I've got my money on the Condenser, problem is new ones are often cr4p quality
