CTD Problem

[pinner2010]

Having tried out just about every combination of MOD list that I could to get over CTD problems, I ended up with the list below, which appeared to be working OK. However, it has just started to CTD for no apparent reason after 10 to 20 minutes. I was wondering if any kind skipper out there could spot anything I missed?
