Question about 1993 Mitsubishi Diamante
When was the timing belt last changed. ? could be this.
also check breather lines all of them there may be a blockage.
check spark plugs and leads this can also lead to this fault. an damaged or week lead or spark plug will take more to get going. leads can wear out and go hard and crack inside. spark plugs gaine in the gap size over time.

I fixed mine by cleaning the throttle body. Just take the hose off of it, spray some throttle body cleaner in there, and wipe it out with a VERY clean cloth. Then replace hose. Piece of cake.

although i cannot send you the file i have found you a manual. Go to PDFTown.com and look for the Verada Magna Diamante manuals. This should suffice for most of your need with your car. Once you download it you will have to open the setup files to get the actual PDF file that you need. Hope this takes car of everything you need!

Very possible it was the timing belt. If the main serpentine belt seems loose, it also coould be your pulley. If you can check it now, the tensioner pulley is the one you see that is very silver looking on the side that actually supports the OUTSIDE of the belt. If you can go take a look at it now, grab ahold of it and try to move it. The only motion it should make is a spinning motion....this will be step one on figuring out the problem....will take one minute to verify.....

Check your ATF cooling system. Your transmission fluid is overheating. This might be after a hard drive. The fluid might need to be replaced too.

SOURCE: car cutting out from cold start
You need a 10 mil and 8 mil spanner, carb cleaner and mabie some wd40.
Remove the big hose which goes from the throttle body to the air filter housing. Under the throttle body there is a idle control valve, unplug it, spray some wd40 on the 8mil bolts and take them off. Clean the idle control valve and housing and anywhere else which looks dirty, dry it with a lint free cloth and then put everything back on.
remove the battery negative terminal and leave it off for 30 minutes, this will reset the ecu to factory settings.
On the top of the throttle body there is a black circular rubber screw cover, take that off and there should be a plastic screw.
Connect your battery and start your engine, unscrew the idle speed control (plastic screw) so it revs at 2000rpm cold. When the temp needle reached the middle so it revs at 1000rpm hot.
This should solve the problem, if you drive around and find that you in 4th gear, with your foot off the accelerator and the idle is going up and down madly then the idle control valve is worn out and it needs replacing. Cost around £125 on ebay.
