EFI failure on LCD

[T5AMX]

Hi can anyone help??
My LCD says "WARNING EFI FAILURE"
It all appears to run ok however on a right hand bend or roundabout it appears to run on 4/5 cylinders sometimes, however on a LH bend or a bump it goes out back to normal display (revs etc) and then it comes back on again so it appears it has a loose connection somewhere but where do i start looking??

Any ideas please fellow Tuscaneers

Ive just read all the threads on EFI Tuscan and nothing relates to my fault..
Any help appreciated please

Thanks
