if had the same problem years ago on a nissan 280zx. car would just die when it got hot. once engine cooled, it ran fine.
 
not even sure if the jimmy has the same thing but the problem was (if i remember correctly) the ignition module. i remember it was a small black electonic module that sat on side of the distributor. easy replacement and fixed the problem.

I have had my 2000 GMC Jimmy in the shop now for 2 weeks... starting to figure it out
I had the fuel pump replaced about 2 months ago... still having problems with starting after it gets hot... Mechanic just replaced the wiring harness for the iginition switch, and it starting throwing codes right and left... mechanic thinks the main computer brain for the Jimmy went out.. will post as we know more.. just wanted to give an update... Good Luck

FWIW:
 My '91 jimmy would start and run until it got up to temp....then die and not restart until cool. I pulled the codes and it said something about the "temp. read -15 degrees" or something to that effect.
 I replaced the temperature sending unit to the ECU (brain) and all is fine.

Check Engine Light by goodwisl

I have a 2005 GMC Canyon light duty truck and the engine light is on. Went to Autozone and they gave me the following problems?
1. Purge or vent solenoids defective
2. Check connector and wiring
3. Fuel Saturated vapor canister
4. Failed EVAP vent solenoid
 
They said it could be one of the above. My question is how much does replacing/repairing any of these costs? As you know, auto shops are charging anywhere from $49.99 - $89.99 to check to see why the "check engine light" is on. I don't want to be charged for that since I already know what the problem is. Also, they may try to incorporate that cost into the repairs anyway if they knew that I didn't know how much it costs to repair in the 1st place. I've been going online but still can't find assistance with costs.
Thanks, Sue

well one day shut it off, went for lunch, then it wouldn't start, poured gas in throttle body, it would run till gas ran out, so I disconnected the inlet to the fuel filter and tried starting, but no fuel came out...
went for some supper called tow truck, while waiting with the inlet line still disconnected, i tried starting and gas started pouring out?, so i connected fuel line to filter and it started no problem drove it home.
  
Next day started no problem, drove around town, came home shut it off, and wouldn't restart, this time poured gas in throttle body and still wouldn't even start this time, "scratching head"
  
check all fuses, replaced relay, disconnected fuel line and re tried, no fuel coming out...
Left for a few days, went out tried to start started right up, tried 3 times then wouldn't start with or with gas in throttle body, i have ordered a new pump, and have changed fuel filter, just not sure why it all works one day then nothing, what really gets me is it will crank over know but seems to be getting no spark and no fuel, even pouring gas in throttlebody wont run, hmmm
  
Any help would sure be nice.
  
thanks
