older gulfstream 1987 sun vista
I was given a 34 foot 87 sun vista with a chevy 454. Only has 25,000 original mileage. My wife and I took it for a twop test camping trip. Everything worked fine, and actually ran very good. Had been setting for a year. we drove it approxomitly 160 miles and ran beautiful. got off the interstate and it started acting like it was running out of gas. I filled it up, and started home. after about 5 miles, started acting like that again. I was able to drive it home, about 25 miles, but I am wondering what would cause that? Has a new fuel pump in it, would it do that all of a sudden after running perfect with a bad distributor cap? any suggestions on what to check, or try is very appreciated.
