Trying to diagnose a problem with my daughters 1998 Beetle. She was on her way to school and had been driving for about 15 minutes when the car died. It would start but only run for a few seconds and then die. Her gas light was on so I asked her to put gas in and it still wouldn't run for more than 5 seconds. The car was towed home and later that night I jumped it (she left the flashers on) and it started ok so I let it idle for about ten minutes and it stayed running with no problems. Tonight it started ok so I took it to put gas in and as I was leaving the gas station as I accelerated it stalled at about 3,000 rpm's but did not die. I drove it around and it will accelerate slowly up to 4,000 rpms but under load it will stall at about 3000 rpms. My buddy has an autolink scanner which he said worked on an Audi so I would think it will work on Beetle. I won't be able to borrow it until Saturday so is there anything I should check in the mean time. Just got the car and I'm still going through it but plugs and wires look recent. Car has 135,000 miles.
