I had a problem with my integra i felt like a dumb ass when i figured it out to.. i would drive around town fine but if i got on the gas, it would sputter then die.. and crank right back up.. on the interstate never failed, hit about a mile on the dot it'd loose power, put the pedal to the floor and it's slow down.. then die.. hit neutral crank it up and good for another mile.. Turned out the rotor in the distributor cap was very wobbly loose.. I dont what motor your running, but pull the cap off and check the points under there sand them down or just replace the cap and rotor, rotor should come with a new screw wirh locktight already on the threads.. that screw works its way loose rotor gets to wobbling it wollered my rotor's screw hole out I had no choice but to replace the rotor... and it'll throw your brain for a loop trying to figure it out, you wouldnt think it'd act like that due to the rotor.. try that.. If that dont do it.. break out a multimeter and a wiring diagram and get to checking continuities..
