got issues

Hey got a 1994 Bluebird SSS With the KA24de motor with auto gearbox. The car wants to go for a little while and stop ( same amount a time each time ) then come back in about 10mins and start and drive home park it and now it won't go. The computer tells me that its the cam shaft positioning sensor but its clean as a wistle wires have good connection(checked on Voltmetre) HELP HELP HELP
