Starving for Fuel or Dead Ignition?

I have a 94 Integra LS with a vtek engine. The car sat for several years and last month I replaced the ignition coil, battery and fuel pump. It ran great till this morning. On the interstate the power suddenly fell off like it was starving for fuel. I was able to limp the 14 miles back home on back roads.

All the while the car would run for about 1 minute and then begin to sputter, loose power and come to a stop. At times it would stall out, back fire slightly and coast to a stop. Once it sat for about 1 minute I could start it and it would repeat the process. At one point I even got a police escort to the parts store. LOL. Changed the fuel filter, car started right up and ran for about 5 min. Took for a test ride and it started all over again.

Any ideas??
 
a similar thing happened when my o2 sensor wiring melted and shorted out. check that wiring and fuse.
 
The igniter is in the distributor near the coil. The best way I know to test it is to check for spark when the engine shuts dies and won't start. When the igniter fails it will usually be due to heat buildup causing a high resistance on the internal circuits.

If you have a heat gun you can try to start the engine when cold to verify that it runs. than shut the motor off and remove the distributor cap. Using a heat gun (or a burly hair dryer) get the igniter good and hot. Than quickly install the distributor cap before it has a chance to cool down and see if the motor starts and runs.
