Ok gentlemen...took out accelerator pedal blew it and cleaned it ,put it back in same problem ticks over ok but rev it for 4 to 5 revs and suddenly cuts out then heator plug light on dash flashes after it cuts out ,....now ive noticed that the self primer pump if thats what it is comes on afterwards if you leave the ignition turned on after it cuts out , i did clean out the filter before this to rule it out it looked pretty clean too ,..so do you think it is a fuel problem
