2000 Yukon dies abruptly while driving

[plambeth]

I'm seeing several posts pointing to fuel pump or perhaps the fuel pump harness, but wanted to ask if the symptoms might point to other possibilities.

Symptoms are as follows:
- Driving normally, and vehicle simply dies (no sputtering, etc - just dies)
- Then starts right up, and away she goes.

This is the first instance it has occurred, so no 'trends' so far. It would seem to me - electrical, just cuts out. I was thinking fuel pump relay or something of that nature.

I'm going to try digging up the diagnostic codes tonight - but any other possible issues I might look at?

Many thanks.

Check both ends of both battery cables. A loose battery connection can cause what you are seeing.

What size motor? I have a 8.1 and it did the same thing with no codes. It was the crankshaft position sensor. Pain in the butt to install but havn't had any problems since.
