1999 C4 3.4
A couple of times recently I've driven for about 30 minutes, stopped for about 30 minutes and when I've gone back it won't start. I fitted a new battery about 3 months ago, so it turns over really well and generally starts straight away. I've tried opening the doors and locking/unlocking to see if it's an immobiliser issue, but that doesn't seem to make any difference. Last time I was at home so left it about an hour and it started straight away. Today, after some messing about it suddenly started after about 10 seconds turning over.
Any ideas guys please.
