The transmission fluid was drained/changed and that seems to have helped some, although there are times that it still 'quits' (btw, the transmission is automatic - I forgot that in my first post), but it is better.
The fuel filter was replaced about a year and a half ago.
Also my boyfriend & his friend wanted to change the transmission filter, but when they tried to do that, it wasn't very accesible to them. Does anyone have any tips or info on doing that? Thanks again...
