got this car about a month ago, it runs great but all of a sudden it cuts out. i noticed today just before this happens the fuel goes down a little then when i restart the engine it shoots back up. also when i start engine i can hear a sound of liquid kind of rushing through also can hear it when i rev the engin. it always starts first time even in the coldest and dampest of conditions. any ideas of what the prob could be would be appreciated. ange
