The Ranger stalled while driving. Took a few minutes to start again. Weird

[Angry Possum]

I went to go drop off some recycle at our Town Hall center yesterday. While pulling into the facility my Ranger conked out like it ran out of fuel. I noticed that I had 1/4 of a tank left. I tried starting it a few times,,, no good so I waited. I had power/electric, so that wasn't the issue.

I was listening for the pump when I turned the key without cranking it and I didn't really hear it engage perhaps due to possible outside noise.

After about 10 minutes it started up again with no issues and I drove home fine. The only thing I can think of is my Evap line isn't hooked into the charcoal filter yet, it's running halfway through the chassis rail. Does the fuel pump on my Ranger have a shut off feature if there's an evap issue?

FWIW I have been driving the Ranger for about 180 miles with no issues. I replaced all the fuel lines a few weeks ago along with a new fuel filter, sending unit, and a new fuel pump.

Could it be possible that I have a new faulty fuel pump?. I had purchased the fuel pump on Rock Auto. I didn't get the cheaper pump, but I got a midrange fuel pump. I'm not sure if the original ECU was replaced, so that's what im thinking could be the issue. However I do have a backup ECU I purchased on Rock Auto few years back, just in case I needed to replace it. Any ideas what to check. Thanks

Question: Can new fuel pumps crap out and or run sporadically? I never came across this before, that's why I'm asking.

This is the pump I purchased.

Yes.

First gen and 4th gen do not, so I'd be extremely surprised if a 1993 does.

Also, FWIW, heat shrink tubing dissolves in gasoline.

Not sure how you wired that one.

Heat shrink tubing off the fuel pump or evap line? I'm not sure what you mean.

If you wired your new pump in with heat shrink on the wire splices, it has dissolved.

Not sure if you wired it or used the factory connectors.

For what it's worth, I wired it directly to the connectors of the new fuel pump using the original wires, I had no issues with the original fuel pump. So i figured if I'm replacing the sending unit I may as well put in a new fuel pump.

The Fuel pump hasn't had any issues in the past few days. I'm removing the bed in a couple of weeks, I'm wondering if I should order a new fuel pump to keep it safe. Your thoughts..

I may try and change the fuel pump relay(s) I noticed there may be two total. If so can anyone advise the correct part or parts to purchase.

Regular old relay, either 4 pin or 5 pin. Inly needs 4 pins. Nothing special.
