Currently I'm having an issue where the car will run fine for about 20 min. then die out on me.

I have a 99 boxster with 125k miles on it. Currently I'm having an issue where the car will run fine for about 20 min. then die out on me. If I wait about an hour the car will start right back up and drive no problem for about anothe r20 minutes or so. No CEL or anything, I've already replaced the fuel pump but same results. What else should I look at?

Sounds to me like you have a bad crank sensor failing when it gets hot.

I'm going through the same thing. I have already replaced the crank position sensor. I am going to have Einar run a scan and try to figure out what's going on. It's very frustrating.

We ran the scan and it showed the MAF Sensor was bad. I had cleaned it since all of this started but not replaced it. Apparently cleaning it was not enough. I replaced it yesterday and all is good. The car seems to run better as well.
