Apologies to all -tried to edit title and text but could not get back in last night.
I had my first on the road problem with the Stag yesterday. Since we owned it it has run impeccably except for 2 brief 5 second hesitations over 6 months ago.
Took the car to an event about 20 miles away and ran ok on way there but after a mile or so on the way back the car lost power. The throttle was virtually unresponsive. Pulled into lay by and opened bonnet but nothing obvious . Checked leads etc and fuel filter was full. Set off again and for first 1/4 mile car ran ok ! But then returned to loss of power. Really struggled to get up any even shallow incline. However I noticed that if I lifted off the throttle on a descent on overrun the car then ran ok for a hundred yards or so . I limped home and left car for 10 mins . Further underbonnet investigation and checks of leads again revealed nothing obvious. Started car - ran ok . Drove round local roads and all ok for about a mile or so but then power loss returned.
My initial thoughts are that not enough fuel is getting through to replenish float chambers. So stopping and restarting or lift off on overrun gives chance for some fuel to get into float chamber and car runs OK for a while before being starved.
Hope to be able to investigate further later today by checking flow to carbs etc.
Do you agree that symptoms are indicative of fuel starvation? Otherwise I assume ignition system is suspect (Lumenition)
Apologies again
