It could be the ignition module located inside the distributor.

After putting gas in my car it wont start

I can think of a couple of things that may be the problem.
1. Reset the computer by removing the + and - battery cables, leaving them off about 5 minutes. Reset the cables & start the car. Sometimes they get out of computer sequence and have problems.
2. If you ran the tank too low prior to filling up, you may have some trash in the line caught in the filter.
I wouldn't consider the fuel pump, because when it fails you cannot start the vehicle at all.
Does your check engine light stay on? Does it run rough while driving, or do you just have trouble getting it to start? If it runs rough, it could be spark plugs or the control sensors on each spark plug.

Engine will run fine for a few minutes then cut off.

If you have good spark at the plugs then it is vacuum or fuel.
1 vac listen for hiss in the few min it runs
check lines for damage, splits, unhooked etc. don't forget under car and dash

2 check fuel pressure, check for fuel delivery to the cyl. remove spark plug crank and check small look for fuel. remove coil wire so it won't start on you.

- When was the last time this car had a tune-up? Could be as simple as that. New spark plugs/rotor/distributor cap/condenser might do the trick.

Other causes could be:
- bad fuel pump relay (definitely first on the list of things to check, and cheapest to fix)
- clogged/old fuel filter
- bad fuel pump

Car is missing and cutting out. Also It has no power.

You may have bumped a wire or vacuum hose causing your problem. Look in the areas where the plugs and wires are and check all connections and hoses. Look for missing or damaged wires and hoses. Be sure your routing of plug wires is correct.
