Won't Start...Need Help

[Martin64]

I have a '70 C10 with a 350 ci motor. Has fuel, has spark, won't start.

In March while I was home on leave the truck started and ran fine. Went to take my son to school, truck started and ran for about 30 seconds and quit. Now that I'm home I checked spark. It has spark all the way to the plugs. Has a little under 1/2 tank of gas. Pulled fuel line off at carb, turn motor over and shot fuel about a foot out the end of the hose.

Any ideas?

Anyone in San Diego area wanna give 'er a look? I'm located in El Cajon just off I-8 and Hwy 67.
