most likely oil drain back problem causing the gauge to go out, but the lack of power is probably from the high pressure oil system. What year is the truck? If its 03-04 might've lost the pressed bearing in the high pressure oil pump itself. When this happened to me, I had these exact symptoms.
If it were just the gauge without lack of power, I'd say replace the pressure sensor, they're known to go out. Truck wouldn't run without low side oil pressure, but to be sure you have it, take out your oil filter and stick an extension or screwdriver down to the plunger. Have someone crank it over, if the bowl fills up with oil, then your low pressure gears are working. That would at least point you in the direction of the high system again. Best way to find the leak is with an air test through the ICP port and command the IPR closed. If this truck is 05+ then I'm really not sure. Don't know if the STC fitting would kill the pressure on the dash. I only know what I've already been through on mine.
