Question

Help answer this question below.

I have an Acura 1987 that starts fine but after the engine warms up it loses rpm and eventually stalls. I cannot restart the engine until it cools. There also seems to be a reduction to the amount of horsepower.

    If you haven't solved it yet it could be a few things. It could be the crank angle sensor, if this goes bad the PGMFI light on the dash will go on. It'll cause your car to stutter and eventually die until it cools.

    The other possibility is the main fuel relay. When these were made they soldered the contact points with inferior solder, after years of heating and cooling the solder cracks and doesn't make as good of contact. The result is when it is hot inside of the car the fuel pump won't kick back on until the car cools back down. Listen for a buzzing noise (the fuel pump) when you turn the key, if you don't hear it then it is most likely your main relay. You can replace it or repair it.

    Is it running hot? Maybe overheating?

    Bad oxygen sensor or fouled fuel filter! Not enough fuel to air ratio!
