My D reg mark 4 ticks over fine for hours but once I drive it for a couple minutes it stalls and fails to restart for about 5mins.it has immobiliser which is working fine..I have recently put a fuse back into the thatcham alarm,could this be the problem

so I've just been looking through the restoration pics and storeys and notic d that quite a few people seem to alter their trim to the RS or XR3i. I have a mk5 EFI and my plan was to keep her as close to original as possible bu now I'm not so sure. So my question is...........do I jazz her up or keep her pure?

Hi All,   Bought my XR3i project nearly two years ago, MOT'd and taxed. Had a couple of months having fun driving it then took it off the road in July 2013. After stripping the car the main plan was to get the car, body and panels perfect for spraying. Panel wise I have since fitted a new front panel, battery tray, fuse box area with everything else being welded and panel beaten. Areas that have been welded are the full boot floor, two floor welds, wheel arch weld, cut old door and welded
