'93 Mazda B2600i Wont Start

My 1993 Mazda B2600i starts up in the morning just fine. It runs for about 10 minutes and abruptly shuts off. I can crank it at full speed, (Good Batter), and it may attempt to start a few times and then it just cranks with no attempt to fire up. It just turns until the next day morning. Then it is the same thing all over again. I disconnected the fuel line from the out let of the fuel filter, leading to the fuel injectors and was able to fill a 2.5 cup glass jar in about 20 to 30 seconds. I checked the ignition coil and there was spark there. Then I checked for spark at the #1 and #2 cylinders and detected the spark there as well. When the truck runs in the morning, for the 10 minutes that it runs, it seems to be very smooth in its operation. No abnormalities at all until it shuts off. I also listened to the fuel injectors with a screw driver at my ear and herd a fairly consistent clicking of the fuel injectors during the 10 minute operation of the engine. Can any one tell me what is going on?

What happens when you spray some starting fluid into the air intake?
