09 550 efi hi two up engine runs rough in high gear

Hi i am new to this forum I don't normally do this but I am in desperate need of help. My 550 has been on the fritz for six months now. This sounds weird but it will run and drive great in reverse I put it in low or high gear I am lucky to even get it to move without it dying. If it does die sometimes I have to cycle the fuel pump to get it to fire again. I have tried a new coil I have had the battery tested it's been in a local shop for the last 4 months they have had no luck. I have now brought it home and back to the drawing board. Anyone heard of this before or got any great ideas.
