Both Aeromotive filter elements were replaced the same time as the new AEM pump was installed. Pump is supplied with power directly off the battery, 40A rated relay, 30A fuse, 12 gauge wire with the relay triggered by a toggle switch in the dash. Fuse is not blowing. Plumbing:<ul> <li data-xf-list-type="ul">10AN line from the tank's sump to an Aeromotive ORB-10 filter.</li> <li data-xf-list-type="ul">ORB-10 filter attached to AEM pump inlet with reducer. </li> <li data-xf-list-type="ul">Pump has check valve installed, then adapted to the ORB-10 post-pump filter. </li> <li data-xf-list-type="ul">ORB-10 reduced to 8AN, 8AN line forward to the front passenger side wheelwell.</li> <li data-xf-list-type="ul">6AN line from wheelwell to Aeromotive 13129 bypass regulator. Fuel pressure gauge installed in the regulator, which is set to 60 PSI. </li> <li data-xf-list-type="ul">6AN line from regulator to Holley Sniper EFI system. </li> <li data-xf-list-type="ul">Large 5/8" return line from regulator back to tank (needed a large return line when I was running the A1000 with a carb for a while).</li> </ul>[ATTACH=full]5565[/ATTACH] Both those things crossed my mind. The old A1000 did this months ago when I drove about an hour to visit my dad. The same type of failure as this time. I drove an hour, parked for a half hour, drove around some mountain and back roads for about 2 hours, then it died. I started it up again after 5 minutes, made it a little further, and it died again. Did it twice more before I got to a gas station. Topped it off from half a tank to full and it stopped. About 3 hours later, I drove home an hour and it did fine. The catch for an electrical issue is that the pumps only seem to have major issues after a long time running and the first time it ever acted up was with a different relay and power wires. I changed to the new relay and bigger 12 gauge wires a couple months ago. My cousin and I discussed that and decided I will go ahead and swap the relay just to eliminate that as an issue. I lean away from the regulator because I figure it would happen while cold or hot if it were the regulator. I can have the car idling for 15 minutes and never see the pressure gauge even twitch off of 60 PSI. Only seems to act up when driving. I guess it would be worth a shot. It's a fairly expensive Aeromotive 13129 reg, so maybe they would replace it if I keep having issues. Just doesn't seem like it. Then again, it didn't seem like a fuel system problem either lol.</blockquote>
