A miss fire is often caused by either a bad or fouled spark plug or spark plug wire. It could also be caused by a failing coil, it that case two cylinders would miss fire. I would look at spark plugs and wires first.
I had a 1987 Chevy Celebrity that would start and then immediately die. It turned out to be bad fuel injectors. I replaced three fuel injectors and the problem has not returned.
You have a fuel leak somewhere. Look for loose connections or bad hose.
I would suspect low fuel pressure would cause both conditions.
Water can defy the force of gravity and flow uphill. This is possible when a device called a hydraulic ram is used. A wick action such as a rope can cause the water to flow uphill.

try changing the fuel filter
