Problem With MB 300e Starting then quiting

[amh_19]

I have a Mb 300 se, 1990, and i have a few problems with it. Last year we took it out of the garage and it was acting up, it would start for a few minutes and it would quit, you couldn't start it for another 2 hours. We found out that the gas tank had alot of pressure in it, so we took off the cap, then the MB starting to work very well. A year later it is starting to do the same thing. There is no cap on the gas tank so we don't know if there is any pressure. But now it will start, and run, and then if you go somewhere it with quit, and you would have to wait for a period of time before it starts again, it also has some accelaterated speed, when not touching the gas. We suspect that it is the fuel pump, but we are not sure, and where we live there is no service for about 2 hours away. i cannot find any information on the internet, and wondered if yous can help. Thank you

i sometimes have this problem too - it just dies sometimes when making a turn or when drivng along. sometimes also when you rev the engine slightly and the revs settle down there is a distinct thump (think from the driveshaft?) before it actually does settle. any ideas on what maybe causing these ? any help would be greatly appreciated. thanks.
