1993 sil chugs and dies

[dlobryan]

My 1993 van starts fine, idles fine, but after driving for approx. 10 minutes it chugs and dies. It will restart and idle just fine, goes into gear but when I give it gas to take off it will chug. I had gotten lucky enough that it would get me home, but finally quit altogether. It will start and idle, but over 30 -40 seconds it tails off to a chug and dies. The chug is like when you have water in the gas, but I've put 3 bottles of dry gas over a month and no change. I took it to my mechanic who couldn't figure it out. He put in new fuel pump, fuel filter, and ignition switch, but it started chugging on the drive home after I picked it up. Van has 168,000 miles, if that matters.

I have no ideas at all, I really thought it would be the fuel pump but wasn't it. Could it be some kind of electrical prob? The same time this prob started up, the cruise control quit working, interior lights would flicker when I hit a bump, and heat would come from bottom vent only even when upper vent or defrost were selected (horn would also constantly blow and I had to pull the fuse but that was due to me hitting the horn to hard). The guidance temp/direction thing has been fried since I got the van in 1998.

Any help is appreciated.
