Default Analyze My 1/4 mile Time and New Problem

I thought I would again come to the vast knowledge bank on this site. I took the Cobra to the drag strip for the 1st time this evening. This is the first time I've been to the track in over 12 years and that time I was 18 driving a 5.0 mustang with an automatic. So I knew I was going to be rusty. I was only able to make one pass.

Car spec:
427W w/ TWM stack EFI (Perform. engineering built motor)
FAST Engine management system (450 +/- rwhp)
335/17s PS2 on rear
TKO 600
No fancy suspension work (AFCO streetrod rear coilovers)

First to the problem. After making the pass I pulled back into line and shut the car down. It was shut off for about 20min. When are lanes were flagged to stage, I fired the car up and couldn't keep it running. It didn't seem to be hot at all (80 degrees C). After about 10 minutes or so of starting it and trying to keep it running (holding at 2500rpms, it seemed to be ok. I pulled back around to get in line again and it died again. This time I just parked it and it sat for about 25minutes. After that, I decided to call it a day and head home. I did not notice any problems with it missing or anything of consequence. Thoughts???? (voltage, fuel dump issue)

Now to the results of my 1st pass in 12 years
I spun through first, hit the rev limiter, spun a little in 2nd, hit the rev limiter, and 3rd and 4th? seemed fine.

reaction: .5571
60 ft. 1.92
330ft. 5.47
1/8 ml 8.19 @ 94.34 mph
1/4 ml 12.37 @ 117.55

Although I was only able to make one pass, I remember why I love the drag strip and why I could spend all my time there. Thanks for all your thoughts.
