Customer has had problem with cutting out, no pattern to it, but there is a lose of power cuts out but then will re-start, a few times it has not re-started straight away and has had to be left for about 20 min. No code present, plugs leads cap and rotor ok, has had new coil and crank sensor, fuel pressure seams ok and can hear pump ok. Any ideas. PS did have a look at archives but none the same .
