10a ignition fuse keeps blowing

I have a 10A ignition fuse located under the dash in my 1994 plymouth voyager. It repeatly keeps blowing on me. When I first went out on me yesturday I could replace it then drive for about 15 minutes then it would blow again. Now however when I replace it it blow almost immediatly when I put it in Drive and press the gas pedal.

Notice I said "when I put it in Drive and press the gas pedal." because I can leave it in Park or Neutral slam the gas all I want and it wont blow. I can even put into Drive and it wont blow. But If I put it in Drive and press the gas hard or soft it will blow.

Anyone have any Ideas? I could really use some help.

Well the ignition system experiances the most load when the engine does.

So there is clearly a small short in there, that only shorts as the load goes up.

Find the short and fix it :)

You are really saying that it'll idle in drive for a long time, even may putter around slowly, yet when pushing on the throttle it will blow fuse?

I thionk you're saying that it has to have "drive " and "throttle to blow?

Please check reverse and then powwer brake it without moving. Is there any lights that come on when in drive?

Thats excatly what im saying. Although I noticed last night when I Idle for about 20 minutes in drive, it will blow. With engine cold I can go around the block a few times as long as I dont press the throttle, but once it gets hot it will it blow without throttle. I can go around the block forever in reverse with throttle.

This is the 10A ignition feed fuse.

Ok now it will now blow when just put it in Drive throttle or no throttle. But still will go in reverse and park and i can give it full throttle.

It has to be something that comes under load only in drive.
