How long since a tune-up? Any applicable trouble codes? Could be anyone of several issues? I don't know liter size of engine? If you think it is a fuel issue, use a gage and check proper fuel pressure and see if pressure will hold for a bit with everything off. If you have the spider fuel system, that system is noted for problems. I'm not saying the fuel system is the problem?

As a first step you should have the pressure gauge sender unit replaced which has most likely failed prematurely. It is not an expensive part but the OP gauge will not work without it functioning.
If the gauge then shows no pressure I would also have a mechanic check the oil pressure on the vehicle with an independent gauge.
Did you verify that you have proper fuel pressure? Should be around 60 PSI. If pressure is low, ensure that fuel filter is not installed backwards. If fuel pressure is OK, check your injectors with a noid light to see if you have injector pulse. If the truck starts with gas poured into the intake, it is NOT the spark plugs causing the problem. You are chasing a fuel delivery issue, NOT a spark issue.
check the tire pressure on each tire, if one is lower it will cause issues..they use nitrogen now to inflate tires at the dealer because nitrogen doesnt react to outside air pressures like service station air does..(tire will look low even tho pressure is good)..check the lowest pressure tire for wounds to sidewall or roadtread by spraying liqiud soad (like windex) on it and look for bubbles anywhere..plug or replace the tire if a leak is found..good luck
remove and have the injectors cleaned
check the fuel pressure as the pressure regulator unit may be faulty
run a quality injector cleaner through a tank of fuel
Your oil pressure will flucuate with the rpm of your engine. It is generally higher also when the engine is cold as the oil is thicker. This is normal as long as your oil pressure stay in the normal operatting range.
