MANY possibilities . . . your fuel is contaminated (water in gas tank) - fuel filter is clogged - fuel pump is failing - faulty ignition wire(s) - faulty spark plug(s) - you just have to start somewhere and start eliminating possibilities.

Clogged fuel filter.

Driving while angry can make you have a lack of focus on the road ahead of you.
