Stalling problem

[jbag]

91 Gmc Jimmy s-15, 4.3L throttle-body inj. 2 wd, 152K. Auto.
STALLING PROBLEM.
Car will start and runs great for 7-10 minutes. Then sputters and dies. Replaced plugs, cap, rotor. Pulled in-line fuel line at t-body & it's pumping like crazy. Also...when it dies, I can still see fuel squirting into the t-body. After it dies, I check for fuel...plenty of fuel & plenty of spark> This makes no sense? I have spark /fuel, & compression, yet it dies every 7-10 minutes. I did replace the in-tank fuel pump ,filter & pressure regulater at the t-body not to long ago. Whassup???
Thanks,
jon

FWIW:
I fixed it and here was the problem.

check for any codes if you haven't already. It's an easy DIY on older GMs stuff:

The 12 code is just the computer saying hello. The code string starts and ends with 12, usually three times, with the faults in between, i.e. 12-12-12-34-34-34-42-42-42-12-12-12.
Lots of help here:

I then ran the codes .12-12-12-15-15-15-12-12-12

15=Coolant temperature sensor signal indicates a temperature colder than -27? F for 30 seconds after the engine has been running for at least 30 seconds.

Hmmm. replace the Coolant temperature sensor??
Put a new sensor in ($14.61 @ NAPA) and it ran for 35 minutes!!!!!!
Drove it last night with no problems.
