Fuel filter changed recently? If it just started this & you filled up somewhere you don't normally fill up, then I'd try some "heet" additive or similar to remove moisture from gas tank, just in case that's the problem.$5.00 test.

No it is a fail safe. When your oil pressure drops below (on most cars) 30 psi your computer will shut your fuel pump down until you either let it sit for a while and it resets or until oil pressure builds again. Sorry!

SOURCE: 98 Accord won't start
Check the main relay-PGM-FI Main Relay, called a fuel injector relay(a gray little box with a plug at the end). To make sure it is a bad relay, do this: Turn the key to II, listen for a humming sound from behind you. It is a fuel pump working. You should hear a click under the dash after it. It is a main relay click . If you do not hear a click, you car will not start. If you do hear a click, you car will start.
Fix is to take the relay out, resolder the joints and put it back in. Go on www. MarkLamond.co.uk and http://techauto.awardspace.com both sites will show you how to resolder the main relay and where it is located if it is the PGM-FI Main relay.

First off, I appreciate your thorough description of what the symptoms are, ok lets go on. It sounds like your air/fuel ratio is off and is getting progressively worse. I don't think you will get this on the first guess. There are things you need to check out with the trucks systems to help narrow your search down. I don't know the trucks maintenance history but if you know that may help.
Look at the EGR valve, if it is stuck that would let an uncontrolled amount of exhaust gas back into the engine for reburn.
If the CAT is clogged the excessive back-pressure would cause the engine to run richer thus loosing gas mileage.
You really need a scan-tool to help. This type of device would allow you to look at live data and see if the component is operating within the specified range. Also a repair manual would help describe to you, the procedures to test suspected components. If you have anymore questions, let me know.
