Hi Jeff, too many people guessing. You need to do some troubleshooting/tests. Are you wanting and are able to work on it yourself? It's probably not a good idea to guess and buy more parts. When you say "sudden loss of fuel", is that a guess or do you have a reason to say that?
When you are ready and have it in a place/time to work on it. Let me know. If the shop did not fix it, they are not a place to go.

Not sure why you bought a new fuel sender? Also, how does a pump "look" fine?
