Steve,
Does your starter have a solenoid?
The easiest way to check your fuel pump is to give the carb lever a flip. You should see a good stream of gas go down the carb throat. If not, than you have no gas making it to the carb. If your trucks fuel pump failed, you should use up most of the gas in the carb without it being refilled.
When an engine starved for fuel dies, it chokes and stumbles a bit. When the spark stops, nothing happens and you roll to a stop. I had an old Ford once and the electronic ignition went out while driving. It just simply stopped running with no tell tale signs. Driving one minute, silent and rolling the next.
I've never used a gas pressure gauge, so no help there!
Good luck!
Jeff
