2008 wrx died while driving... Cranks, No start

[joemother]

Last week i was driving to the shops and my dash lit up, and then the car just died. Looking back down the road saw a trail of coolant but no hose leaks, looks as if it spilled out of the expansion tank. Towed car home and got to work the next day. Read codes and it threw up P0340 & P0345 which are both camshaft sensor faults. Replaced both and still nothing. Is it possible im missing something major here? Also checked fuel lines and pump, as well as all fuses, all are good. Any help at all is welcome, thanks

Slip one of the cambelt covers off and check the cambelt would be my first move.
