If your O/P sender is screwed into the top of the block, and you used some type of thread sealant for the 1/8 inch NPT threads, you may have an intermittent grounding situation. If you have the VDO sender, run a ground wire to it. If you have a Kavlico, it has a ground wire so just make sure it is secure.
It could be something else, but you need to start with a correctly functioning sender.
