HI,bought my first bimmer 2 weeks ago a 1995 525i se touring, excellent condition, service history bargin.
just getting used to having just under 200bhp on tap(previously owned a landrover v8).
today i accellerated up a steep hill in second gear and suddenly lost all power
when i stopped it was running rough as if fuel was not getting through. turned off and left for 15mins. when restarted it idles fine but when moving it was coughing and spluttering then as sudden has the power went it returned.
it now hessitates a little when accelerating and the cam chain sounds like its hitting the rocker cover, but this seemed fine when i had a look. been used to landrovers where you couldn't hear the radio at 30mph, i can hear every little thing in this.can anybody help?. thanks

The next time it happens, open the trunk and bang on its floor, seriously. The exact thing happened to my dad 540i and it was a failed fuel pump. Also, check for vaccum leak on at your intake boot and ICV. The ICV rubber gasket tends to fail prematurely.
