Hi all i'm new and already got a problem

my beloved 2003 frelander td4 auto has turned nasty on me, packed up 3 times on m4 in heavy traffic, keep getting that horrible ems light up then it runs in[I will try & n get you home mode] but the three times on m4 she packed up on me, after about 20 mins she starts again[bitch] . . . for about a week now she's been a poor starter, fore that she started as quick as a ferret up a trouser leg. . . not had any diagnostics done as yet as I will have to sort out a morgage first. . .any one got any clue's . . .
