Possibly crud in the gas tank is finally finding its way into the fuel pump or carb? Maybe the fuel pump is starting to fail. When I had the 235 in my truck we took a long summer trip (10 weeks) across the western US. Along the way the truck started having the same symptoms and eventually would not start. I pulled the line into the fuel pump, nothing came out. Blew into it, got a little resistance then a mouth full of gas. Reconnected the line and drove about another 5 miles and same thing happened. Pulled the tank and turned out a big glob of solder had broken loose and was rattling around the bottom of the tank and would block the line. Put everything back together but truck did not have any power off idle. Mechanic in the next town said the fuel pump diaphram was starting to rupture from all the running dry. He could not get one until Monday (this was late Saturday) but next largest town had a store open on Sunday where I could get one. We nursed the truck the 60+ miles at 20-30 mph over the pass then coasted down for miles into the town. Replaced the pump is a Safeway parking lot, got invited to a great meal and a shower by a nice Mormon family, and then went on our way the next morning with no problems.
