Have a look see at the fuse box. Check out the fuses labeled ECM, or ECM1, check and replace. The next place I would suspect is the modual in the distributor. This tends to be an issue most of the time with 2.8's, and 4.3's. If all else fails. Check out the oil sending unit, it may be on it's way out. Just unplug it, and give it a whirle. Good luck, hope this helps.
