Help.....

[muzzy1]

Hi new to this.....i have a imported 3.0lt limited auto surf ....and it has decided to play funny buggers in regards to starting and running, i.e. when started it may run for 30 secs then just cut out or when actually driving lose power and cut out ...so i have to put into neutral and start it again this is now getting tiresome and it's been sat in front of the house going nowhere and my heads hurting now bangging it against the wall....i've checked filters including the one on the fuel pump....any suggestions would be greatly appreciated....as i don't want to get rid of it...many thanks....
