Hello again from u.k re my previous post i pulled rcm and yes the connections were a bit dodgy. My local t.v repair shop re soldered the connections, and i thought we had cured the problem. Out on test about the same distance and it cut out and refused to restart. I dont think cps as it spins over o.k and fires up straight away and runs fine no misses or anything. I am now thinking fuel pump relay or a connection making and breaking under heat. Any further suggestions would be more than welcome. thankyou mickmatt
