[gazrat]

In the past nonth it has done this about 6 times.  In the morning from cold it starts first time every time, runs great, now and agian i come to start it when warm and it turns over like a goodun but will not start. Try agian after about half hour, fires up first time. Called the AA out 4 times and had to cancel, it started before they got there. Any ideas help

Hi Gazrat, remove your fuel filter and check for oil deposits in the fuel (very tiny black spots of oil in the fuel, use a torch).  Check for the fuel filter paper element going black from oil deposits too, replace it if it is and see if the starting problem is eliminated.  If it is, remove the filter again after a couple of thousand miles and see if it is becoming saturated with oil again.  Post your results.
