Hall Sender

Well, the problem is that when the rocco gets up to a certain temp (after the raad fan kicks on) the car
shuts off and refuses to start again until it cools down.  I can't give precise temp readings as to when
it will die and when it will start but that's the basics of the problem.  The car will start every time
that it sits.  Tha rocco has no problems starting and/or running like a bat out of hell.  Fuel pump is
new, fuel filter new, tune up done, fuel pump relay non-existent as I replaced it with a fused, switched
jumper wire...other items also replaced but nada...

Like I said, in order to troubleshoot the system, I decided to run through all the tests as per la
Bentley and that's how I came across confusion in regards to the hall sender.  The hall sender failed
the Bentley test...the temp sensor also failed the Bentley test...I can rationalize buying that part new
cuz it's like $10.

If the car starts, that means the spark is there....it may be weak right?  Now when the car gets 'warmed
up' and it cuts out, is it possible that the hall sender is heating up and failing me????  I dunno....I
need to be enlightened on this subject matter...

TIA
