I have 1995 Sho and engine shuts down

[Keith Hutchings]

I have 1995 Sho, it’s our third SHO, when the engine gets warm 5 to 10 minutes of driving the engine shuts down like it’s a lack of fuel. This issue developed after we replaced the gas tank, due to age and leak. We changed the gas pump , tank sensor and gas tank. Anyone have any ideas on what the problem? It’s an awesome car.

If it is fuel related, put some "quick start" in the intake piping when it stops. It will start if it is a fuel issue.

Electronic components can fail or partially fail when they heat-up to operating temperature.

Another long shot is the water pump weep hole allowing coolant on the Crank Position Sensor. That will stop you, and in a few minutes on a hot engine, will dry off enough to run again until its next soaking.

Get some codes using the paper clip method and report them here.

Thank you. I did hit with starting fluid and it fired. So we think it’s fuel related, but if could be a sensor of some sort. Thanks Keith

You can take the fuel pressure at the schrader valve on the fuel rail in the engine compartment. Your best results would be when the car stops or a least starts to act up.

There should be a code, at least a stored code, even if there is no CEL

Often, your current problem is due to the last repair on the car.

engine shutoff after it gets warm is the typical symptom of a bad crank sensor. I would start by replacing that. Good luck finding one though.

That sounds like a good place to start. Any guess location on new crank sensor. Thanks Keith

You can try shosource but they are out of production. Maybe get lucky on ebay a wanted to buy post on this forum. Alot of people are using used ones out of necessity

I've got a used one for my own time of need that I could be talked out of for the right price for the right car, but I would fully diagnose the issue first to see that you maintain fuel pressure through the fault, and that secondly, the pulsing PIP signal from the crank sensor to the DIS module is indeed failing. The timing with fuel pump service is too coincidental, unless that was based on a mis-diagnosis.

The last eBay auctions for these or ones sold through "fan sites" (also Thunderbird S/C) were ridiculously priced.

Clear your codes and pull them again when the engine stops running. That will help in the diagnosis

Yes, pull codes before throwing parts at it. Another how-to source with code meanings:

If it needs a crank sensor the SHO one looks like this https://www.amazon.com/Standard-Mot...DK/ref=olp_product_details?_encoding=UTF8&me=
there are other sensors that pop up in search that look much different and they are incorrect.
Chances are slim in finding a new one. We've been barking about this for a year or two now as all the inventory dried up
