About to open a new thread, but this seems to be the same problem. I have overhauled my 1J engine and the ECU connections with a good result. But I still have the same problem as you, not after 15 mins, more like 1 hour.
I was wondering if we talk about plain dirt in the tank? That would account for the time frames. There are macro filters on the in-tank and out-tank fuel pumps, and what will happen when dirt collects? Sooner or later it will choke the pump.
The second problem is that when you start to choke the fuel pump it will start to draw more amps, thereby heating the relays. I had 1 relay (Toyota, metal housing) that in fact melted the plastic that it touched. I replaces all the relays controlled by the ECU (With Bosch and higher rating), but I still have the problem. The relays can stand the AMP drawing, but still get hot. Strange on a fuel pump relay with very tiny wires.
I think I'll have someone check the fuel tank (especially for signs of "collapses" of the pump filter. I dont believe in coincidences. When my problems start after a certain period, in town or on the freeway, then.... Filter? (The pump will move the same amount of fuel, low speed, or high speed). My main fuel filter has been replaced twice. Dirty like H..., but after only 5-10K Km.
