We have a 2001 L200 that has been having the EXACT same problems. We have had all of the same things fixed to no avail (ignition twice, BCM twice, and catalytic convertor). We finally gave it a shot and had an after market starter removed and didn't have any problems for almost a year.
About two weeks ago, it started happening again. Security and/or service lights come on. Cranks but doesn't start. I'm hearing typing this because it's doing it again! It has done this at least once a day for the last 4 days. I wish I could find a warning signal to know if the car is about to do this.
An added thing we've noticed this time around is that the "trunk open" light won't go off, so we can't use our key fob to lock the car doors. This is a new symptom.
If you find any help, PLEASE post it here and let me know.
