Check fuel pressure at the injector rail. Could be your fuel pump relay is cutting out. If fuel pressure is good, check for sparks at the plug wires. Read the link below for more info. Do It Yourself Diagnosis and Repair
Mine was doing the same thing. I Change the fuel pump and I was up and running again. Then it died again w/ the same symptoms. Thought it couldn't be the fuel pump, it was new...New, but defective. Good Luck
The vortec engine has a time delay fuel pump relay, check that...Was your pressure reading with engine running? Test your injectors. Check the coolant temp sensor, it will confuse the ECM if it is out of range...mainly when the engine is cool. Check the ignition for weak spark, coil resistance. Check the air flow sensor....I would stop using starting fluid immediately, the volatile conditions it creates could cause damage. Hope this helps.
look under the carpet on drivers and passenger sides for the ground blocks. turn edge of carpet next to door over close to front and there is a metal plate with a bunch og ground wires that need to be cleaned for a good connection.
Sounds like fuel pump going out. I was told by a friend that the pump can get stuck and that by knocking on the fuel tank or by attempting to start that it can kick the pump out of the bad spot and it will start. But it is a sign that it needs to be replaced.
If the fuel filter is dirty it will settle when you turn the truck off. When it runs for a few minutes the debris in the filter will get sucked into the screen and stop the fuel from getting through. If it was a starter or coil, it would not start at all.
