Hi i seem to be having a popping sound then followed by a loss of power to my van. It seems to come from under my footwell left hand drive this is immediately followed by loss of power as if the van is going to stall . When i turn the engine off and leave for around 5 mins and start up again seems to be ok at around 50 mph .any ideas thanks.

of course because you would lose compression in that cylinder or a misfire.
