So, I’m driving my 2003 Saturn LW 300 wagon (3.0 liter, V-6 engine) the other day, and the engine shuts off out of nowhere. Luckily, I was on a quiet secondary road, so I drifted to a curb in neutral. Then my car wouldn’t start. Eventually, my car started. I drove for another five minutes, and the engine shut off again–without coming back on–while I was driving. This time I couldn’t get the car started again. I had it towed into a shop. Of course, the car starts up, no problem, in the garage. But while it’s running for 20 minutes, the engine cuts off once again. They started it back up again, and it ran without stop for 40 minutes. The mechanics can’t figure out the problem, and I don’t feel real good about taking this car back on the road, especially since I do a lot of highway driving.
Can anyone offer some possible thoughts about what’s going on here? (A friend’s father had a similar problem with his truck; after taking it to four different shops, one of them finally determind the problem–the fuel pump’s electrical harness. Is it possible I’m having the same problem?)
Thanks in advance for your help!
