Quitting under steaming probaly a dirty fuel filter. Mine would idle fine for a long time buy fail when i kicked her in gear. Let sit and she would restart as normal and someyimes take me a little distance under power. Change those fuel filters i expect your fuel pump is good. The primary filter lets bigger particles thru than the secondary filter. The black stuff in the bottom of your fuel tank is likely compost of particles too small to be trapped by your primary so it may look clean but the particles may not be small enough to pass your secondary filter. Change both filters and if you can see and cause that stuff in you tank to move then you might be able to get most of it out. That would be a bonus. Otherwise carry extra filters and learn how to do the change fast
