Not my month so far...

On top of the problems I have been having with Yeller, my Blazer has decided it want to join the fun too and be a beoch!

Lately the Blazer has been cutting in and out occasionaly on the highway or heavy acceleration. I replaced the external fuel filter and this did not help (going the cheap and easy route for starters). Then I hear that Q-jets are supposed to have an internal filter and not an external filter. So I go to the local parts house and purchase one of them thinking the one in the carb must be clogged. I pulled off the external filter and replaced the section between the pump and carb with a new line. I then pulled off the "cap" or inlet which would gain me access to the filter...only to discover there is no filter in there at all. So based on that, I figured I had not found my initial problem. While I had it apart, I installed the new filter, took it for a drive, and it ran decent...and never acted up.

The next day I take it to work (20 miles each way, in rush hour). It ran fine there, but on the way home I could tell it was idling a tad bit more rough than on the way in. It was pretty hot out, so I figured it was the weather or something playing a role in this.

Now this last Thursday, Shelly and I decide to order a pizza, pick it up, and bring it home. Since it was nice out, we decide to take the Woody. We drove to get the pizza (5-6 miles), pick it up, and head back home. We get about a mile from home and the Blazer sputters out and dies. I pulled over, tried to re-fire it, but nothing happened. I get out and pop the hood, only to hear a sizzling sound. Upon further inspection, I see a puddle of gasoline on the intake manifold boiling like a pot of water. It looks lie it was coming from the accelerator pump area, but i can't be positive since there was gas on on both sides of the intake manifold. I ended up having to run, yes run, home 1 mile, get her Jeep, come back and pick up Shelly and the now cold pizza and warm pop. I then returned wth my neighbor and a tow strap and towed the woody home.

What can I look for to try and determine what happened? I have never actually worked on a Q-jet (I have only had Holley's), so this is quite foreign to me. I already pulled the carb, and am ready to bring it to a local fellow who rebuilds carbs...but since I am trying to sell the Blazer, I don't want to dump a bunch of cash into it if I am not going to get it back.

Once again, seeking any help on this. Thanks in advance.
