Gauge Cluster, low tire pressure light and more

[6pack]

I went onto the beach with the truck last week and aired down the tires before I went out there. The Low Tire Pressure light came on, which made sense. After wheeling, I aired back up. The light stayed on, but after I turned the truck off and started it again, the light did not come back on. That seemed right. Now, the Low Tire Pressure light keeps popping on. Seems to be random. When I start the truck, sometimes it comes on, sometimes it doesn't. Anyone know what the issue is here?

The two other things I've had happen with the gauge cluster deal with the whole thing. Once, driving down the road I looked at my speed and noticed the entire cluster was dead. Nothing was working. That only happend once, about two months ago. Then, last week, I looked down while driving and noticed all the idiot lights were one. In this case, everything was working. That has only happened once also. WTF is up with my gauge cluster?

The truck goes in next Saturday to have the steering shaft replaced and they are checking into this, but I was hoping someone here can tell me what the issue is so I can tell them.

Thanks!
