Hey so today i went to go drive my 300E after letting it sit overnight, i started it like normal and it started fine i let it warm up for about 5 mins and then start to drive. The car was 100% driving good for about 10 mins then when i came to a stop light I noticed that the car hesitated a litte bit to go from stand still. Then i pull up to another red light and when i go to pull of the hesitated a lot and then stalled, i tried to start but it wouldn’t start but after cranking it for a while while pressing the gas pedal the car started. Im not sure what this could be or what can be causing this.

Fuel pumps, fuel pump real, fuel filtersX3, dodgy fuel..............

You need to start some methodical investigations and testing.

Unfortunately no one can wave a magic wand and shout "abracadabra"!

Additionally, there is the Community Search, at the top of the page that you can use, or Google, with keyword search and site:benzworld.org, that will get you a plethora of related hits you will need to sift and read thru.
Provide some history/details too on your ride for members to know, before they play Dr.

Yea it might test something but not pressure or flow under pressure or the fuel pump relay other than the initial prime as the engine will not be running.

Check your EHA.

We've covered fuel pumps, fuel pump relay, EHA, Distributor cap and rotor, how about the fuel gauge? Seriously, these systems are 30 years old and older, are relatively complex, and defy remote diagnostics. Best thing to do is start here:

Wasted bandwidth.
Unformtunately, OP hasn't responded since his first opening post.
Shall we play whack-a-mole in his absence?
