Engine cut out and won't start

2003 Vauxhall Signum 2.0t
Car: Vauxhall Signum
Year: 2003
Variant: 2.0t
Categories: Running Rough, Starting & Power Loss
I was doing about 50mph when my car randomly cut out.
No previous signs just died on me.
Now I can turn the key fully and only battery light stays on.
Tried new battery and new alternator. Checked all connections and all fine?..
Help...

I had a similar problem with a Mondeo, have you checked the relays sounds like its a relay that's faulty, also check all earth connections, also check the bigger fuses 70amp etc.
good luck!!
