Do you live where we've been having the recent deep-freeze? It's possible
that you have very small amounts of water in the fuel system which are
separating out and freezing at low temps. Maybe try a bottle of gas line
"antifreeze" - the isopropanol stuff is said to be better than the
methanol.

Has your "baby"ing included using lots of fuel injector/system cleaner?
This msg

has some innacurate assumptions in the petroleum chemistry and what
injector deposits consist of but the poster's experience is worth noting
WRT the damage to the nylon sock by some cleaners... which leads to "goo"
getting into the fuel lines/injectors.

I hope the above does not apply to you but you need to find out what is
coming out of the fuel lines into the fuel injectors. I'd say an
examination of the fuel filter, which is inside the tank, and the fuel pump
unit/sock is in order here.
