Hello- I have a reinell 240 br 5.7 GXi volvo pents sx. Every time I take it to the lake (3 times) it had broke down on me and ran like crap. Eberytime the shop takes it to the lake it runs great. It all starts for me when I rey to work the trim. starts running like crap missing spurting then eventually dies. I take it to the shop they cant find anything, they lake test it and it run 57 mph with no problems. lol This is killing me softly...I don't know anything and really appreciate the advice I get here. I tell the shop everything I get here. Any ideals. They have put it on the computer and keep telling me until it happenes for them they dont want to buy a bunch of parts and start replacing ( I agree)...Thank you
