Answer 1
When it dies, I is obvious it has fuel, does it continue to have spark? -
Comment 1
Thank you again for your quick response. Whats the best way i can check that? If it helps i did plug one of those little flash testers on the jet plug. it kept flashing as it died. -

The safest way to check without tools (scope, or spark checker) is to take out a spark plug, connect it to the spark plug wire, lay the spark plug on a ground and start up the vehicle. You should see a blue spark jumping from the electrode to the ground. Be careful, that ignition system can put out 50,000 volts. Be careful if there is a fuel leak it could ignite. -

I'm not sure if what you are describing is what is happening to my 92 Chevy G20. When weather is hot outside it sometimes dies after starting. I drove it 50 miles, ran great, went into store, came out and it started dying whenever I started it. After about 6 times was able to quickly put in drive and go. Was told it was vapor locking. Still waiting on help about this issue in my question I posted but thought maybe you might be having same issue. Good luck. -
