Engine loses power, dies, but restarts in a minute, Diagnosis help please? Options

Happens when idling or driving. After 5-10 minutes, the engine loses all power, stepping on gas pedal does nothing. Engine dies. Restarts like nothing in wrong in 10 to 60 seconds and runs great for another 10 minutes.

74 1.8 L-Jet. Bosch 2 port updated fuel pump. Just getting it back on the road after being under a cover for 3 years. It had old gas, which I drained and replaced. New fuel filter after new fuel. The fuel pump was replaced 4 years ago, but only about 1000 miles on it. Old gas was, however pumped through it. I just replaced the fuel filter again, thinking it might be clogging up from the lines being rinsed with the new gas, but it made no difference.

You need to get a fuel pressure gauge to make sure you're not chasing the wrong system. Sounds like fuel but.... If you are losing fuel pressure you can discount a bunch of other things. Long time ago a customer brought in his '75 with a similar problem. Ends up the fuel lines got swapped at the tank end. a leaf was floating in the tank and would get sucked down over the unprotected return port which then shut off all the gas. As soon as the engine died the suction stopped and the leaf floated off for its next visit. No idea how long the lines were crossed but one leaf got in somehow and caused a lot of headache.
