Hello,

 

I am a little lost right now. I have a 1990 998cc Mini. My engine starts just fine and drives well but at time would have a hard time at idle and would start to cut out. It is common for at time to start cutting out and dying at junctions, traffic lights, roundabouts etc, having to restart many times, it then just have a hard time or not idle, though runs fine under load. I did have this problem in the past but went away on its own but now i think it is here to stay.

How well serviced is it? Always start with the service parts first so plugs, leads, timing, dash pot oil, valve clearances earth points etc etc
These all need to be in tip top condition any way and will fix most basic running issues and they can then be ruled out as causing the problem of it persists

A good tune up as mentioned above is a good place to start. Moving on further, worn throttle spindle in The carb is a classic example of causing this. A carb rebuild will save the issue, if it's not a simple tune up related problem.

What’s your idle speed like? Too slow perhaps

If it is cutting out with lights etc on, I agree with dyshipfakta - increase the idle speed a tad.

If it happens when the engine is warm, I think I would be looking at the coil first of all.

Good luck

I had the exact same symptoms as you and it turned out to be caused by worn throttle spindles on the carb. Ream the old ones out and press new ones in. Replaced and now the car idles perfectly.
